The prior generation are very solid balls also. Still have about 3 dozen of those and 5 or 6 dozen of the generation before that (the last generation before they changed the name from B330). Heck, I have played every generation of the RX model so I guess you could say I am a pretty big fan of them. Haha
yes, I LOVE the B-X/XS line...i'm trying to build up my new ball stock for the year...i'll probably grab two boxes of the new ones, 2 of the old and 2 dozen of the new QSTs since they still have those tester sleeves at $10 a piece...
