Hello,

Yes please do show AndyF's head numbers. It would be nice to see them in the same thread for easy comparison. Especially since this one is for the archives. Absolutely great post.
Thanks Dwayne

Damon

is it Indy's VJ that sucks? the backcut that really helps? the chamber and bowl blend or combo of all 3 that makes such a big difference?

I had never seen this before, this needs to be in the tech archives or best of as well.

Thank you Dwayne!
