Will be interested in what you think about this one. I demo'd the 330 version, loved everything about it except it felt just a tad heavy at times, just right on the edge of my comfort zone. But absolutely loved everything else about it; very comfortable, solid, good controllable pop, fun-serving... so I splurged (though wasn't as expensive as I thought it would be) and got the 310 version from TW-Europe. Been in love ever since (3 months ago). Actually added a little tape at 12 for some extra pop on serves, and the gut/poly in there is sublime. Sure wish Yonex would see fit to sell the lighter version over here; think they would find a nice following.
