I bought a used rig with a Saphire 2 main with supposedly around 700 jumps made Oct. 03. This was from a person who normally sells gear on here, not just an individual selling their gear. Canopy had a a new line set 80 jumps ago. The canopy was inspected. 4 jumps after the inspection the main ripped out the bottom skin on the 7th cell and stabilizer. The person who I bought gear from said the would "stand behind the gear" He knows of the problem and talked with the rigger who inspected the canopy after the tear. Of course the seller will not return my calls or emails now. What would you do?
