Start packing now.
You are jumping big forgiving rigs now, as compared to that new elipical you might have in a couple of 300 jumps. If I were able to choose which rig I would preferr to mal because of a bone headed packing mistake, its a rig loaded 1 to 1 or lower.
Normally student / rental rigs have enough jumps on them that the material won't fight you. Unlike new Zero P, learning to pack is hard enough. Unless you get a new canopy in said rigs.
I have several friends who still can't pack after a 1000's of jumps. Which isn't bad as they can aford to pay a packer, but sucks at a boogie when the packers are backed up. Plus if you are jumping your ass off and the packers are busy I could usually beat the packers if I packed for myself.
Hey maybe its me but I want to understand my gear and when your new there is nothing like looking at a canopy over and over to know what is what instantly. Makes reviewing any issue easier to say name a part of the canopy was wrong, than to say that line hooked to that thingy did not look right.
When asked who I trust more packing me or my packer, she wins everytime. Truse me she rocks, but I still trust myself to pack.
Finally why learn twice. My girlfriend learned to pack and caught on quickly, then quit packing. Around jump 100 she decided to start packing and had to start all over again. I stayed away for a while. Repeating a class sucks.
My opion, learn it and stay current.
