Re: [chicago] Ace vs. Fox vs. Flik
I assume you're looking for a comparison of the unvented FOX and Flik? Because otherwise it's kind of an apples-to-oranges comparison (vented Flik or FOX where the Ace is unvented).
Assuming you're asking about the unvented form of each:
The Ace has much better slider down pressurization than either, but especially the Flik, which in it's unvented form has very poor pressurization.
The Flik has shorter, snappier flare. The FOX also has sharper flare than the Ace, but not by nearly as much as the Flik.
The Ace has slightly better glide than the Flik, and noticeably better glide than the FOX.
The control range on the Ace is wider than either FOX or Flik, but especially wider than the Flik. This makes the Ace easier to sink in for accuracy, but harder for most skydivers to flare (since the long flare is not very similar to the flare on a skydiving canopy).
The Ace is manufactured by Performance Designs, which matters to some people. Personally, I've never seen any quality problems on FOXes or Fliks, so that's not at the top of my agenda.
The Ace is substantially less expensive than the Flik or FOX ($1459 for the Ace 260, $1800 for the Flik 266 or FOX 265).
I am a dealer for all three of the above canopies, and own multiple examples of each.
