Good points.
So I guess I spend $6k +++ and get one butted Ti and one straight gauge Ti and then I'll know for sure, right?? That's certainly not happening!
I gather from the various reads and links that the difference is rather insignificant and not worth the extra $$ ? Just get what you like and fits, ride it, enjoy it and don't look back?? Unless someone more knowledgable than I can refute, that seems to make sense.
