I don't use it very often (at least in winter) but it's a fantastic FH option when I don't need the HSS and LSS that the FD3 brings. It also allows me to have more HSS/LSS than an FD might provide if the wind has gotten up but I still want the same type of distance
I can see where the FD2 might be nice for forehands but since I'm probably 95-98% backhand it just didn't do anything special for me. My FD3's are Doombird III's and they're flat and not nearly as beefy as you would think. I actually get a similar flight and more distance with them than I can get with the FD2 so I just couldn't justify sticking an FD2 in my rotation.
Maybe I should drag my FD2's out and try to throw them forehand and see what happens.
