I have been jumping the Xaos 27 for over 2 years, 3000 x-27 jumps, and must say it is exceptional, especially openings.
Continous HMA lines rule (no cascades), and pretty easy to replace line sets without sewing. These lines also last longer. The swoops are total fat long daddies with lots of low end lift, basically alot of power at the very end of your flare so you just keep on flying.
Long and strong! If your an experienced canopy pilot then don't take my word for it or anyone elses. Check it out and see for yourself.
