Re: [BASEMenace2] ACE vs Seven....
I've done over 200 jumps on aces, probably 350 on sevens, both zp and standard, and I currently own a zp blackjack. Here are my personal experiences on there canopies:
ACE: great overall canopy. Free fell some pretty low stuff with it including a 113 foot tard. Never had any issues with the canopies until I started doing some low static lines with friends with vented canopies. Great slider up as well with consistent openings.
Seven: "the new ACE". I say this because I put it in the same class of an all around canopy. Lighter weight and even easier to pack than my aces. Interestingly I've found the opening height and time to controllability pretty much exactly the same as my aces, I do notice that even though it's open, flying, and controllable, it does tend to take a little longer for the nose to completely pressurize. I've also found that this does not seem to happen with the zp nose. As has been stated, the glide and flare are amazing on it, and especially half brake approach into full flare. Do this on another canopy and then a seven to see the difference. This is my go to canopy for the majority of my usual jumps.
Blackjack: the static line and low free fall beast. The reason I got this canopy, and the best argument I could give for vents is if you plan on free falling sub 300 on a regular basis, or do a lot of low static lines. I've jumped the non-zp and own the zp. Obvious downside is that the pack volume is bigger than an ace or seven. I'd say my 260 zp bj packs just about one full size larger than my seven.
Not condoning one canopy over another even though I have a relationship with asylum, just giving my review of the three. Only canopy I don't endorse for low free fall is a ragged out non vented fox, that shits just scary.
