Before I get a plethora of members commenting on the risk and recklessness of downsizing or high wing loads with low jump numbers, let me preface this post by explaining my background.
I haven't jumped in three or four years (due to college, lack of money, life, etc.) and in my brief history of skydiving I've only made a mere 36 jumps, but I've made it a point to myself that I'd be back in the air this year. While I'm going to take all the necessary steps/courses/jumps I need to become current again, I went ahead and bought a used container (with reserve, no main) that I found on this forum. It was built to my exact measurements and weight, and holds the same size canopy I used as a student (170). I've read literature online about wing loading and its effects and such, but I wanted some personal anecdotes from skydivers. This is where you guys come in.
I'm about the same weight I was 4 years ago, 140-145lb, so my exit weight is at about 170lb. The student canopy I used was a Sabre2 170, so wing loading is at 1:1. I can still remember at that time I felt the 170 was really big and slow for me, which was probably attributed to my low experience and over confidence, but I always wondered how I would handle a 150. The load would be 1:1.13. Now, this is what I'm wondering: does that extra .13lb/sqft make a world of difference? In terms of numbers, it seems really miniscule, but I really have no idea how that translates to actual performance.
I figured I'd just keep my eye out on a deal while I work my way to becoming current again. I'll still be using student gear for some time while I save up money for a main and AAD, and I'm sure my DZ won't let me use a rig with anything less than a 170 for a while. I'm in no rush, and I'm not opposed to sticking with what I know, but it's just the question of difference in wing loading increments is one I've had for a while. As for my intentions for the canopy, I'm not interested in swooping or high-performance landings - I mean, really, I'm still a novice - I'm asking because I want to know what I should be looking for or avoid while I shop around.
Cheers
