I agree with part/ most of what you are saying... but i wouldn't go so far as to say stock cyls eat cubs MOST of the time.
Unless you are saying that when a stock cyl DOES eat a cub its due to setup ,,most of the time.
Or are you saying stock cyls eat cubs most of the time?
Not trying to bust your balls,just trying to get a clear understanding of what you mean, so the OP can get the best advise.
