Re: [Freefly69] ACE DAGGER Or ????
If you are only jumping largish Antennas, it may not be worth your while to invest in the bottom skin inlets.
Bottom vents aid in cell pressurization, generally yielding cleaner openings and faster time to riser responsiveness. They can also aid in overall inflation speed (which only really matters at very low altitudes). They also cost several hundred dollars extra, so if you're not going to be doing things where they really come into their own (low stuff, solid stuff, and especially underhung stuff), they may not be worth the money for you specifically.
If I was buying an unvented canopy for that kind of thing, I'd go with an Ace. In my opinion, it's got the best unvented inflations on the market (mostly because it was designed first as an unvented canopy).
If you are opening the field up to vented canopies, I'd go with either the Blackjack with ZP foreskin (as Peter recommended), because that's my personal favorite canopy on a wide cross range of criteria (best inflations, good penetration into wind--which will matter on your antennas, strong flare). If you like the way that the Dagger flew for you, you also ought to consider the Apex (previously Vertigo) Rock Dragon. While it doesn't appear to have quite the penetration of the Dagger, it has significantly superior inflation, and is probably (given that you were pleased with the Dagger) something you'll want to check out. Plus, it'll likely mate (sizewise) well with your Warlock.
I've jumped all three of the canopies you asked specifically about (Ace, Dagger and Troll).
I didn't like the Dagger's inflation (I felt it wasn't clean enough), and truthfully, I wasn't too comfortable with the swoopiness of the canopy (although I'm sure that's a personal preference issue). Note that I have made a very limited number of jumps on the Dagger (less than 30, and none of those canopies were my own).
If you are going with the Troll, I'd definitely get the MDV (bottom inlets) option. Without it, I was most unhappy with the canopy's inflation (both slider up and slider down). The MDV pretty much addressed these issues, though. I like the Troll's flght characteristics (good penetration, good available forward speed in full flight, good sink in deep brakes, good flare). I have several hundred jumps on the Troll (including a good number of both MDV and standard jumps, and a good spread of slider up/down).
For flight characteristics, I like the Ace the best. I also think that, unvented, it has far the best inflation of these three (unvented) canopies. It does have more available forward speed than the others, which some folks don't like (personally, I just pull the toggles down a bit more, which seems to address the problem). I've been very pleased with the openings, the flare and especially the responsiveness to riser input. I like the Blackjack even better. I've made roughly 50 jumps on Aces, but several hundred on Blackjacks (which pretty much fly the same).
Bottom line? I'd recommend an Ace if you go unvented. If you want vents, try to get both a Blackjack and a Rock Dragon to demo, and see how you like each.
