I love mini drivers. For me, easier to hit, longer and more forgiving than a standard 3 wood with similar workability. Compared to a driver, again a little easier to hit, more workable with distance that is between your normal driver and 3 wood (depending on the loft you use). I've tried heavier/shorter drivers and just prefer the smaller mini driver head. For me and my buddies, we don't care how many clubs we have in the bag so there's always room for these niche clubs. Now I carry an 8 deg driver, 10.5 deg mini and a 14 deg 3 wood - I could easily ditch 1 or 2 of these clubs and still score the same lol. For me, its nice to have an alternative for a short/tight par 4 or one where a full driver would get me into trouble. As well, i struggle mightily hitting a draw with my driver so if a draw is required, I have more luck using a mini driver or 3 wood. My normal driver is typically a 46.5-47" and on most days its easy enough to hit and not much harder than a standard 45" ,but everyday is different. I figure if I put enough clubs in the bag, at least one will work š
