Thanks, that was my understanding as well. Wanted to give the Urethane balls a try before moving back to Surlyn, only about three rounds in on the Tours and generally played well, got a weekend trip coming so I'll let that be the decider. I tried the Tour Softs at first since my understanding was they were the closest Titelist offering to the NXT and they were too soft for me. Maybe will peak at the Tour Response or Qstar Tour before making the jump back to Surlyns (Vice Tour or Q Star) if things don't improve with the Maxfli.
