I've only put a few jumps on my brand new Safire2 so far but I love it. It's my first canopy (189 loaded at about 1.1:1) and I think it's perfect for me as my first canopy. Fun but not stupid!
I was jumping a Pilot188 as a student before finally getting onto my own gear and I have to say the difference between those two canopies really surprised me. The openings of the Safire are a lot softer. The toggle response of the Safire is better. The glide of the Safire is WAY longer which makes for landings that are WAY more fun.
I'm still a newbie and it's obviously still a bigger canopy, but for me, the landings are awesome.
I'd like to jump a Sabre2 just to feel the differences. But from what I've heard the Safire does have a better glide and flare.
So far I love it. I'll post again once I have a few more jumps on it.
UPDATE - I've put about 70 jumps on the canopy now and just love it. Openings are consistently awesome. I've taken a Sabre2 up a few times as well and have found that the Safire2 does have a little more drive and seems to level out earlier in the flare. Because I'm still new to the sport I know that I'm not flying the canopy any where near to what it is capable of BUT, I have been able to pull off some great no wind landings on straight in approaches or with a very little bit of front riser. I will definitely be sticking with this canopy as I downsize and learn to fly more aggressively. Loads of fun.
The only downside I'd mention (that really isn't a negative, more of just an observation) is that the vectran lineset is already looking old and dirty compared to the spectra lines on a main with similar jump numbers.
Update - I went from my Safire2 189 to a Spectre 170. No Thanks. The Spectre had FANTASTIC openings but it's just not meant to fly like the Safire2....and it doesn't. When it was time to downsize again, I went back to the Safire2. Now on a Safire2 149 loading at just over 1.4
LOVE IT. This canopy is awesome. I've been doing lots of front riser carve-in landings and this thing is great. Can get some really nice speed/surf on landing. Obviously it doesn't swoop like more extreme or smaller canopies but it'll give me a nice long ride across the ground at my loading. I'm certain that I'll be on this canopy for at least 300 - 500 more jumps just learning to fly the crap out of it before I downsize again. Glides forever. The openings are amazing. Almost feels like my old Spectre. Consistently 800 - 1000 foot openings. (some don't like that but I'll take 'em.) Sub terminal openings are a little crazy feeling though. You can have a coffee while you wait for it to stop snivelling.
Did a few jumps on a Sabre2 - didn't like the openings and it didn't glide as long as the Safire2.
Anyway - love it. Would buy it again in a second.
