I just went to the future and came back. 2 yrs after Fed retired nobody even talked about the 1hbh anymore, let alone thinking about switching.
Don't pick it just because you have seen it on TV. I haven't seen a rec player with 1hbh does it in a way that beats 2hbh'ers into submission. Most slices about half of the time and when hitting ts 1hbh it is just a defensive or neutral shot. I don't play with 5.0+ ppl, and I don't see a lot of 5.0+ 1hbh either.
