Hi mate sorry to bother you, I have been searching for ages on here trying to find out how much I can mill my head on a js440 bottom with a js550 top.
and I came across a post with you talking about your 3 skis.
so I'd like to no how much you recommend I mill my head by for it still to be a reliable ski.
it has a full westcoast exhaust system with water box dual cooling etc.

Hope you can helps any thanks Steve
