Interesting to see Mona having an extreme top spin forehand grip compared to today where she almost uses a continental grip to hit her forehand.
I love her FH (the FH motion and the easy power she generates with that shot). It's a great attacking weapon. She can generate so much pace effortlessly on her FH wing. The biggest issue with her FH is that she can't defend at all with it. Maybe that's because of her grip. I'm not sure.
Overall, I wouldn't say her FH is a weakness. It's great offensively and poor defensively so yeah overall it's not bad.
