Aerodyne Research
Aerodyne makes the popular and versatile Triathlon. This is a very nice 7-cell Zero-P canopy. It has great flight characteristics, flies well at slow speeds, and you can sink it into a tight landing area. The fabric feels a little weird- almost kind of tacky. This helps prevent the slipping and sliding Zero-P canopies are notorious and makes it much easier to pack. As an added bonus, Aerodyne has a packing video available that is much better than "Pack Like a Pro." This is an excellent packing tape which you can get for $19.95 ($25 for PAL). BTW, I am not getting paid for that endorsement. Amazingly, you can actually order a Triathlon online! I think this is the first gear manufacturer making their products directly available online. You might still check the prices you get from a dealer, though. The online store looks like it charges full retail list price- something you should NEVER have to pay.

Flight Concepts International
Manufacturers of 9-cell, 7-cell, "Total Performanc" Zero-Ps, and reserves. To be honest, I don't know that much about theses canopies. I know someone who jumps a Maverick (200 sq.ft. F-111 7-cell), but I have never jumped it. Other than hers, I have rarely seen Flight Concepts canopies. They just don't seem to be too popular around here.
