What is the best diameter?

Ive heard a lot of things, from a lot of different people, but there doesnt seem to be any real consistency in what the best diameter for an inner barrel to be is. Ive been told 6.01 is the way to go, and Ive also heard that 6.07 is the one thats best for snipers. What is true, and what do YOU use? I personally have a 6.01 and have about a 2 inch grouping at 110 feet (after which it declines rather rapidly).

And rather than just saying the the best diameter, a little explanation as to WHY would be nice ;)

Your 6.01mm TBB result is identical to my previous data; drops at about 100ft, but quite accurate anywhere before that distance.

6.03mm is the best diameter that I've concluded.

This thread can shine a little more light on my tests and results:
What is the weight of those steel "BBs"?
