Nowt wrong with Air Arms Mark, they're actually on my doorstep in Sussex :-) that said, I do really like the Hw97 although mine developed accuracy issues after a couple of thousand rounds, it's currently being tuned by a chap at my local range. Quite strange really as I'm starting to hear more often that the stock spring is not great, some folks have said possible quality control issues??? None of that with the Air Arms Prosport ;-) it'll be interesting to do a detailed comparison between the 2 rifles when I pick her up Friday...
