Have several hundred jumps on my Xaoz21 loaded at 2.3 or so. Openings are consistent and very easy to hold near on heading. It does open different, progressing from the outside to the center in a see-saw manner. I've jumped Triatholons, Stiletto's, Vipers, Alpha's and a few others in the last 2000 jumps and I like the opening on the Xaos the best. Only had 1 malfunction due to the HMA line grabbing the BIG tab on the slider's kill line, Other than that just sweet.(straight pro pack, roll outside 3 in 1 full turn, nose open and even with outer rolled noses, and quarter the slider, pull nose of slider out 2" and cacoon it. I use super bands - no problem.
Flys very fast and desends very quick. You need to have it together or you are out of time. For ref., if we all open at 2500 I'm on the groound and picking the canopy up and the rest of the guys are still at 1200+. NO SHIT!
The front riser pressure is reasonable and you can add more most of the way thru 270s and 360's. Done be supprise to hear your Pro-ditter going off as you are turning the corner to land!!
Rear risers are very light and you need to use caution.
I've heard PD claim their prototypes on HMA lines need relining in 100 to 200 jumps. My line show little wear more than 250 jumps.
Packs easily into my TJN could easily go into a smaller container but my Dash M-Z's 135 reserves are about as small as I want to fly.
IF - you have the skills, this is a sweet canopy.
