Its the longest driver I have ever hit, even longer than the MacTec NV3. I found this driver to be very forgiving as well but because it is so hot of the face it seems to get out of control more than the average driver. I had a Fujikura 584HK installed and it brought the flight down and tamed it a bit. If you play the ProV1 X with a high kick shaft this driver is tuned to kill all others out there. I would love to see the results of the long drive contest and the margin it won by if you have the info.
Chris, thanks for the info. Unfortunately I don't have all the info of the contest. Read about it in a local magazine recently - the contest itself was quite popular here in Thailand (sponsored by a local major energy drink called Lipovitan D). They also show highlight in local golf program on TV. Contestants are all amateurs and I understand most major club distributors are basically sponsoring all these contestants by providing clubs for the contest. It gets real good publicity like this one. The guy who won it I believe hit a 334 yards - may not be big by the US standard but given the playing condition (soft fairways) it's pretty darn good. All other 11 contestants didn't even reach 300.
