Query: Recoil, recoil, and more recoil

I just purchased this nailer on the advice of a dealer. They said they changed the headvalve design to generate more power to compete with that new Bostich tool. I tried the tool at 90 PSI into Timberstrand and the recoil almost caused the top of the tool to hit me in the head! This is by far the worst recoil of any tool I have owned. It also failed to sink the nails flush in the material. Luckily the dealer took the tool back and ordered me a Bostich N88 which he said the salesmen demo'd to him into LVL against all the other framing nailers he had and the Bostitch tool won hands down! I am eagerly awaiting it's arrival to test.
