Just a fun Poll.
Personally, I play with one handed backhand. I started playing back in the day, when SV was the way to go (so to speak). So most of my early training was all about Serve, Big Forehand. My backhand was always the weakest shot and only late in my years I started to pay some serious attention to in.
Nowadays I feel very comfortable with my BH. I actually think it is my more consistent stroke. FH is still my preferred shot, mostly because I can control the placement and spin way better and can put some serious heat on it, but it is the one that can break down more.
