BP and a few others mention the wide arc and more freedom of movement to crush TS 1HBHs, but you guys are in the vast minority. I only see one guy (a coach) at our courts who hits a hard agressive 1HBH. The rest, including the guys I play, hit slices or poufy flat 1HBHs. Why have a liability like that? That was the exact reason I switched to the 2HBH. I can still hit a slice 1HBH if I want. Anyone can do that.
Maybe that is the potential beauty of a good 1 hbh.
When playing against 2 handers, you expect to see topspin, but against 1 handers, it is significantly more rare.
It probably is a liability, in that I agree with you, that the 2 hbh is hit much harder and with more topspin by more players, but I find that just like hard flat serves, after a while you get used to it and adjust accordingly. What you initially might have had trouble with, you now punish, unless your opponent can provide enough variety to keep you from zoning in.
I find that most 2 hbh players that I've played lack some of that variety, I get into a zone and try to make them pay.
On the other hand, they see my 1hbh and don't expect heavy topspin.
Admittedly, I don't play at a high level (3.5-4), and until warmed up, I hit a fair bit of low back/side slice to their backhand, in an effort to get them to have to dig down low, which most of them don't lke to do. In many cases, they have to go to a 1 hander.
Once I'm warmed up and hopefuly have them kind of out of their zone, then I start to mix in some heavy topspin and if successful, then the fun begins.
Bottom line, I guess, is that if you can hit better than decent top spin with your 1hbh, along with a variety of back/side spin slices, then stick with it. Otherwise develop a 2 hander.
hope this makes some sense?
