Dgdavid,
The written review is on the way! It is in the middle of editing so look for it in about a week.
I talked to Chris and he enjoyed both the Pro One and the Formula 100. If he had to choose one, he would pick the Formula 100. He said he liked the 100 because he was able to get amble amounts spin and power. He though the Formula 100 was similar to the Babolat Pure Drive but found the 100 had added comfort and feel. Lastly, the ability to easily customize it was a big plus.
