Hi guys, thanks for that. My 08s's have the 49mm pistons. I have run a 28" bar on one, on a years dead 4ft diameter oak, slow but did it well. So, this 07 i'm getting has more power, great! K, Steffen, i'll scout out Atom an Nova. Erm, hope u lot r going to be ok, having voted in the Donald. Cheers.
