Do you feel the tip section will tighten up or won't make much difference
how sensitive are you to 3/8" of a change? i would think that depends on you whether or not you can feel it?
Frank said 2-3 CPM, can you tell the difference between 2-3 CPM? If you can, then go for it...if not then why does it matter..tip it? If anything, make it a little stiffer if it gets loose on you and butt trim if its perfect. Or..you could split the difference

if it plays perfect
kind of hard to answer; doesnt it depend on you?
