The Atomic looks quite good but although I've not held one I've shot an Aim-X and a Falcon FN8. Didn't like either of them much TBH. Too big and poorly balanced for me. Big numb things, I think the main problem is they're too top heavy, they're really just cut down PCP rifles. I have to say too that 25 shots at 5 ft.lbs is quite poor. My modified Rohm Twinmaster gave over 60 shots at 4.8, and was really nicely balanced. Now Nick has sorted the only drawback with modifying the Rohms (that of venting on firing with no pellet) that's where my money would go ... if I didn't have a Steyr!
