I have been jumping all sorts of 170 canopies for about 25-35 jumps I'm not trying to downsize cuz of the "cool factor" with it I have just been flying my 190 for a while and am def comfortable enough on the smaller 170 mostly because I'm not that heavy, i only weigh 150-155, 175-180 with gear...I continuously have end cell closures and sometimes center cell closures and have asked everyone of the packers at a few of my local DZs and everyone tells me it's a wingloading issue not a packing issue because the canopy is only using what it needs to too catch me and so the closed cells don't need to open yet so I have to correct this...I would prefer a pulse 170 but haven't had luck finding one in good shape or cheap...I saw an add on here for a trade so I wanted to ask what others would do hope this extra info helps with more answers Blue Skies:-)
The diablo is the only canopy ever that scared me. And I had 800-900 jumps at the time. It is I believe the canopy with the most roll action, ever. Not a canopy you want to make low steering mistakes on. A friend of mine had to cut my diablo away after the canopy opened fine, due to linetwists after undoing a bootie. He loaded it at 1.8~ but you get the picture... I'd stay far away from one at 167 jumps that's for sure.
Also the storm is worth much more, given similar condition canopies.
would you trade a 190storm for a 170 diablo? seems like its a good canopy but just want to ask around
I don't think Diablos have any redeeming qualities. John LeBlanc reduced the toggle sensitivity of all canopies (Velocity, Katana, etc.) following the Stiletto because he observed jumpers having issues with roll stability on landing. The Diablo is even more sensitive and lacks the Stiletto's flat glide and plane-out which made it pleasant to fly.
This ignores market values (low for Diablo, higher for a recent PD design).
It also ignores that fully elliptical designs are inappropriate for people with under 300 jumps. That's because an elliptical will quickly point itself at the ground when told too whether or not that's what you want and at that experience level you're likely to have issues with muscle memory being sufficient to avoid over-controlling the canopy in stressful situations.
Here's a Stiletto 150 fatality at a 1.2 pound/square foot wing loading.
The Diablo is a VERY aggressive canopy. It loses more altitude in a turn than pretty much anything in a similar size. It turns VERY aggressively.
At less than 200 jumps, I'd stay away from it if I were you.
It also requires a great deal of attention during the opening sequence. It is very sensitive to body position during opening. It will twist up if you aren't symmetrical. And if it twists up, there's a really good chance it will point itself straight at the ground in a high speed spin.
It also is unstable across the roll axis while the brakes are stowed. Which means if you initiate a turn with harness or rear risers, it will not come out of the turn on it's own, but will increase and steepen the turn if corrective action isn't taken. And it's very sensitive to turn input so it will enter a turn very easily (read: unintentionally).
I wouldn't, and I loved the Diablo I had for several hundred jumps. It's a great canopy if you want something perverse that turns really, really fast (see all the descriptions), and does nothing else notable.
