2750!!!???
And you're worried about spinning 710's on the stock heads??!! I haven't done the math but I'm thinkin that the loading on the blade grips (and bolts) at that speed would have to be pretty close to the same as spinning 710's in the 1900 to 1950 range. I think this means that your stock setup is a lot more solid than you give credit to, John.
