i have about 500 jumps on a 84 fx,and about 150 on a 89, 20 on a 115 and 20 on a 78. i load the 84 at 2.2 and i have 50found that i got ok proformance on the 115, but i under loaded. the 89 gave me good proformance and good swoops, but when i jumped the 84 i was in love. it was great, i could just go forever in my swoop. i just got my 78 and i think i can swoop farther under the 84. the speed if a lot faster, that why i got it. i still have my 84 to keep around when i need it. but it takes quite of few jumps to handle one of these. i don't want to sound like a sky god or anything but i would say at least 500 jump with a lighter loading. but if you jump one then you beter be ready to buy it because you'll want one.
blue sky's and long swoops
