I would like to know the bottom of bore to ground dimension for the 915Hd - typically 1" on your fairways. Also the target head weight of the 17.5 with the stock 9G weight, around 228 grams I'd guess. I may build one long and light (2G wt.) to replace my last fairway. For the record I've played Titleist fairways for the last decade, currently have a "tuned" 18º 913Fd that's killer, but I'd like a little more consistency. With my swing I see the same distance with a 1" shorter hybrid vs. fairway, less carry but more roll.
