Really. I would love to see you prove that. I don't think the differences are that noticeable and I'd suggest if you were to slip a Bridgestone B330 RXS into the mix you wouldn't tell that one.
I can actually remember the last time I played with an RXS (10th and 11th of Bearwood Lakes). And it was certainly a distinctive feel! Not to my taste. I certainly could never tell the difference between the earlier incarnations of Srixon premium balls Z-URS, Z-URC etc, nor the equivalent B330s, nor actually distinguish the difference in the 2 brands!
I'm prepared to take your challenge (distinquishing the 2 AD333s) on for a £20 donation to H4H if you have the cahones! As Fundy posted, 3 putts (probably less) and I'd easily pick the difference!
