I've been working real hard on which driver to replace my gamer with and intend to finalize things very soon. In my testing, one of the best performing candidates consistently swings 2-3 mph slower for me than my gamer or the other top candidates. It's consistently slower over several test sessions, hundreds of swings, with several shafts and flexes. What's perplexing is that I get stellar ball speeds and distance off this slow swinging driver (it's tied for first on average) but I assume there's maybe another 10+ potential yards if I swung it as fast as the others. The driver head just feels light, and I seem to lose feel of the head after transition. I sense it's lighter feel might be leading to me losing lag and load versus the other drivers which is costing a little head speed. Is that plausible? Might adding a few grams to the club head help me? I'm one whose transition can get too quick and I also struggle to maintain lag to impact. Thanks.
