I was thnking of repowering my 90cm Sporasub, it came with 22cm bands and want to replace them with 19 cm bands to give it more punching power...what do you guys think? The gun came with 16mm dia "H. Dessault" bands, could I use a different brand and get a 20cm band or will this cause the barrel and shaft to flex. I'm new to euro style guns and need help! Thanks for your input....good luck, shoot straight, and be safe!
