Ok, gotcha.
Lot's of guys that do good port work for money on here.
My two favourite port guys are Mastermind (Randy) and blsnelling (Brad). I give them a plug because they share exactly what they do and help guys that like to do things themselves for fun.
Randy does his own machine work and that is what you need if you want the fastest saws around. Brad has a great recipe for porting the 261. Both are real gentlemen. There are tons of other guys that do porting as well so look around if you want.
Now, you have so many saws you probably can't even use them all enough yourself to even break them in in a timely fashion. So, I would say you should pick one or two to be built as balls to the wall fun saws.
Thank you!!
