Anyways I'm not criticizing, just offering my $0.02. Should be a good thread as is!
The available option for me was to go with stock 10.5:1 or the JE 11:1 Comp ratio. For you on the m52 it would've bumped the c/r from 10.2:1 to 11.5:1 which is a bit bigger jump in compression then I would've received so it really wasn't worth it.

That 11.5 would have been a suitable improvement, but I couldn't find a source with that C/R piston.
