  1. The "hole in the leg wing/deflector" functions the same way as the leading edge slot on the airplane wing. It provides smoother, cleaner airflow over leg wing in order to generate additional lift. Additional benefit is, as Jarno mentioned, cleaner and stronger airflow for pilot chute extraction and increased lateral stability. The result is very agile suit. Downside is that suits equipped with this slot are not that suitable for back flying. More on slots can be found on number of aviation/aerodynamics pages, like: http://www.grc.nasa.gov/WWW/K-12/airplane/flap.html Wikipedia is helpful as always: http://en.wikipedia.org/wiki/Leading_edge_slot

    Dragon

    Dragon is a tapered 7-cell, designed to combine good characteristics from classic 7-cells and elliptical 9-cells in one canopy. My girlfriend bought Dragon 150 as her first canopy, downsizing from student 210 sq ft (she is 160 cm, 50 kg - 5'4'', 110 lbs). But before giving her the canopy, I made first 6-7 jumps, at wing load of 1,25 (I am 85 kg - 185 lbs). Canopy has very smooth, consistent openings, always on heading. It flies great, and I estimated that glide is equal or better then PD Spectre. Toggle inputs are light, but the canopy is quite responsive (also, more toggle input is required then on elliptical 9-cell). It is also stable in deep brakes, and rather difficult to stall. It is also very predictable canopy, no nasty surprises. I tried hook turns, and to my surprise, it was possible to make some very decent hooks, with long flare and enough lift at the end of the flare to climb a little, just enough to touch down softly (no running required). Front risers are a maybe bit harder then on my Radical 135. My girlfriend's transition to new canopy went smooth and without a single problem. She immediately fell in love with it, finding it agile and responsive, and enjoying very good glide, nice flare and great openings (just wanted to share her impressions, of a skydiver with only 50+ jumps). Later I had a chance to jump PD Storm 135, which is kind of high - end tapered 7-cell, and I think that Dragon is not so far behind (at proper wing loading, of course). It is great as all-round or transition canopy, and would be also very convenient for WS jumpers, due to consistent on-heading openings. I would always recommend Dragon to novice jumpers.
