Hey Kris, I was having the same issue with my Mirage and a 24” pc on a Stiletto 135. I even have video of someone IADing me and pc in tow for 4-5 sec. I switched to a 30” F111 and it fixed my hesitation problem about 90% of the time. I don’t believe the pc is the problem, but the bridle getting caught on the corner of the main pin protector. I have since changed my bridle routing and the problem is fixed 100% of the time. Instead of routing my bridle directly under the closing loop, I make a 45 degree angle down to the right where it can just barely be seen with the flap closed. I hope this makes sense and helps you out.
Also a 28” zp or 30” F111 pc won’t hurt. Another problem I was having with my 24” pc and Stiletto 135 was line twists. I had 0 line twists for 200 jumps with the same canopy, same pack job, same rig, same pc, etc. I all of a sudden started getting line twists about every third jump. The 30” F111 pc fixed my line twist problem 100% of the time. BTW, I still have soft openings with my Stiletto 120 using the 30” pc.
The reason I choose F111 was PD claimed more consistent openings with F111 vs. ZP to me over the phone when I was troubleshooting my line twist problem. They also state “Pilot chutes made of zero porosity fabric are more sensitive to specific design criteria, and two of similar size may have widely different drag”.

I have the canopy at my house now. I plan on taking some pic’s and posting sometime.
My guess is line dump. I stopped counting after six broken lines. None of the breaks were at or close to the stitching, mostly directly in the middle of the line. Most of the broken lines are on left side, including all of the three sized lines. One of the left steering cascades broke, and the right steering line broke at the toggle loop. One line broke at the leading edge of one of the center cells then tearing the cell about three feet. One of the center line’s binding tape tore directly from the attachment point.
I would blame the lines until I noticed the steering lines, binding tape, and torn material. We plan on sending the canopy back to Precision soon.

This was my teammates canopy and has less than 30 jumps on it. When he first received it, it took 2000 feet to open. GZ said all 135's had similar characteristics and the hole in the slider was a standard modification. After further inconsistent and slow openings, Galaway told my teammate the canopy is not safe at his low wing loading and sent him a Nitro 150 to test (not GZ Nitron, but almost the same). My teammate was trying to sell the canopy and allowed the demo since the guy had sufficient skill set and wing loading. The guy made two uneventful jumps on the canopy before the mal. I also know he changed out the slider, but I don’t know if that was before or after the uneventful jumps. Even though the original had a hole, I know the Xaos has a much larger slider than most other canopies and curious to find out what size slider was swapped out. It did have all three line sizes, 352 on the inside, 440 on the outside, and 946 for brakes. I understand the small lines were the ones busted. Also curious how hard the opening was. I have had bruised ribs and a busted chin without breaking spectra. I don’t think most people know the difference between line dump and a stiff opening.

Back in October I was looking for a new canopy and debated purchasing a Nitron. I did some research to see what other purposes the lines were used for and I found the best comparison of the material from various racing sail web sites. I then posted my findings (see attached file) for feedback. George quickly responded to me personally, stating my information was incorrect, as you will see below. I then gave him more detailed information and inquired about getting more information about his products and he never replied back, nor referred me to someone else. In short, I decided not to make the purchase.

Hi Greg,
I think you might be confused about this. The Xaos utilizes a High Modulus
Aramid fiber, nothing like Aramid fibers used by North Sails. I just wanted to mention this so you will know. Information like this is generally very good for all skydivers, but in order for it to be properly useful, it must be accurate. I will try to get some info for you (and others) about our High Modulus Aramid braid.

George-
On the contrary, I saw many references to the High Modulus Aramid fiber on Northsail's site. I copied some of the verbiage below. But I hope you don't think I was trying to degrade the HMA lines on your canopy. If anything, the article mentioned vectran as being obsolete and I saw it was a complement to your choice of lines. Although I am interested in the Spectra 2000 they mentioned. I got a chance to see one of your new Xaos canopies Sunday and I was amazed by the size of the lines. That is what prompted me to research what other uses it may have. I thought the article was informational and thought it would be worth sharing to others. I do think more information about the lines could be beneficial on marketing your new line of canopies. On another note, I am in the market for a new canopy and would be interested in your company's suggestion on a Xaos. I have been unable to find any comparisons on the flight characteristics of the different canopies. I have over 500 jumps on a Stiletto 135 at 1.4, 15 jumps on Stiletto 120, and 9 jumps on Crossfire 119. If you could let me know who to contact in your company for recommendations, flight characteristics, and demo information, I would greatly appreciate it.
