Sort of along these same lines for me. I'm not at 2.5 but in the past year I've passed under 5.4 and 4.4, both of which are threshholds for qualifying tournaments I've always wanted to play. As long as I can stay under those threshholds, and ideally keep going down (there is another qualifier available to me at 3.4, as well as at 2.4 and 1.4) then I'll be happy and keep entering those qualifiers. But if I don't, then well, it's not a huge deal either.
Got mine in the mail today. Will test out tomorrow or Sunday. They certainly seem like they're okay on the surface. I do really like the feel of a urethane ball regardless so that's probably why. Not very useful info I'm sure. I'll let you know how it goes but it'll be at most one round of data which probably also isnt useful.
