I have had 3 sabre 1 150s and 1 sabre 1 170. the 170 i loved it opend well and landed great. as for my 150s i loved them all but i have not jumped one in a long time because i an sick of being in pain from the openings. out side of that there are the best all around canopy for night jumps, new jumpers, windy days, and high alt. landings. i have landed mine over 8000 feet MSL and it did just fine!
