Hello, I am new to skydiving and looking towards starting my AFF training next week. My local DZ doesn't have student gear to support my weight of about 260 pounds. I am looking at buying a rig from a local. The main is a firebolt and the reserve is an angelfire both by jumpshack. The main is a 290, modified tandem. Do you think this set up will be OK for a first timer? What is the lowest size you think I should go? Thanks.
