I absolutely LOVE this mold. It fits my hand perfectly. I carry 3 F Model S drivers, 2 BaseGrip and 1 DuraFlex. The 2 BaseGrip ones I have, 1 beat-in and one nearly new, give me an understable and straight flight respectively. The BaseGrip plastic seasons evenly and consistently, allowing for multiple stages to be bagged to grant different flights. The BaseGrip is fantastic in moist conditions, has great grip in hot humid conditions, and has just enough skip. Depending on your arm speed, most players will get a slight flip-up, maybe a tick or turn, then a good solid forward finish on their FmS. My 10yo son carries a 163 BG FmS as fairway and control driver and loves it. With these being so readily available, you can easily grab multiples or get replacements should the need arise. Check out the video clip below. I throw a new BG FmS (too nose up to see a true flight but you get the drift) and a well seasoned BG FmS. They both have similar distance potential but completely different flights. Overall, I prefer the BG over the DF for this mold because I can cycle through them as they beat-in and have a huge range of flights from a single mold.
