Played the prototype balls received this week--seemed firmer than ProV1's I normally play, but overall score was good (74 on a par 70).  9 fairways, 12 GIR--seemed like low spin as drives were fairly straight and overall distance on irons seemed greater, although temp was ~ 90 degrees.  In comparison, feel around green was not as soft as I prefer, but very glad to have the chance to participate in the prototype testing.  Hope I can get one more round in before responding to survey.  Thanks Titleist!
