I'm looking for my first rig. I'm 5', 6" and 200 lbs. muscular build. I'm currently training and will be back to 180 lbs. shortly. What size main and reserve should I get? Also can anybody tell me what my harness size is? I'm also looking at a Lazer 7 cell. Is this a good canopy for a begginer? Thanks for any info on this stuff!
