Ok, so thinking of going for WCS M7 v1.0. It's a pre broken in edition, with what seems to be the older front bearing (can't find any other difference between the v1.0 and 2.1 unless someone knows better!). Thinking of giving it a go as my club engine and upgrading it with new front bearing and fresh rod shortly after a couple of club meets. Any reason REDS keep upping the version and modding' it? Any Intel' appreciated.

A big fan of picco motors (yep, had a few P5's in the 90's!) so guessing this will be a damn good lump.

Thanks for any comments, will keep you posted to how it runs.
