Hi King K,

I can't really recommend giving your wetsuit the chop. A fullsuit is designed with quite a different upper body constructin in mind than a Long John. You'd be cutting through the middle of arm gussets, back stretch panels, and chest panels and this would leave a real mismatch of ends to tidy up. Lets say that you could cut all the arm away, and then get someone to build a roll over cuff to stop the trimmed ends from disintegrating, you'd then have a badly fitting LJ (these panels aren't deisned to end where they now end), and you'd probably find it an expensive alteration.

My suggestion would be to sell the old suit, and get a new LJ, Something like an Instinct LJ is well priced. (of course I'm totally biased working for Ironman Wetsuits)
