... back to Rob's initial spec question ...

The main 77 of mine that I see the shift with is all 25mm internals and V-Mach spring / guides / seal and still has the original Transfer Port of 2.9mm.

The Bigtoe style 77 has 25mm internals and a V-Mach spring and seal ... but custom made guides ( rear one fits inside rear block ) and has the TP opened up to 3.8mm. Not seen any shift in that but it's not had that much put through it.

That TP help settle 'repeatability' re bounce/surge?
