Kyle, I have a CFX in .22 in addition to my .177. Both are brilliantly accurate rifles, and as Vince mentioned, they are easier to shoot than the RWS break barrels (although, both my 34s are tack drivers). Being a fixed barrel rifle, the CFX is inherently accurate. They also do not require a drooper mount. Power wise I would estimate my CFX in .22 and my Panther to be pretty close. I guess it just boils down to which you prefer a fixed barrel or a break barrel
If you do decide on a 34, and want to use the BKL mount, yes, you want the 260 D7 mount (if you are using a 1" tube scope). That six screw, one piece mount is the answer to a RWS shooters scope mounting nightmares, in my opinion ( I have owned 3 RWS break barrels and I won't consider anything but the BKL mount, pricey but worth every penny).
