Thanks mate, I've yet to take it to a game until tomorrow, going to see what the fps is like, I have 3 springs to take with me, all made by guarder a sp90, sp100 and sp110. Already got a few modify improved hop rubbers and a maintenence kit from novritsch. Done a small test shoot with it on semi and full auto and I'm very pleased with it, very little deviation in the bbs at 20m. Tomorrow will be a better test of how it shoots as it will be used in its first game.
