I also use Tibhar Stratus Power Wood. I have G-1 on the backhand. I have used MX-P. Yes I agree MX-P is faster than G-1 but also less control. G-1 also lasts a long long time, compared to MX-P. G-1 also has more spin than MX-P. I used C-1 which a bit soft to G-1 to get used to it and eventually went to G-1 for the speed. Never tried S-1 or P-1. I just never felt the need.
I have tried Tenergy 05 fx on the backhand. Too bouncey. My push will go off the table. I tried EL-S, Rakza 7, Rakza 7 soft, Baracuda, etc. for my backhand. Don't remember much. I have always gone back to G-1.
I have stripped G-1 off my current blade after 6 months to put on some of my older blades to fool around at the club and surprisingly those G-1 rubbers are still pretty grippy!
Sorry, I have never used any Victas products.
By the way, recently I started using Tibhar Fortino Performance with the same set up (H3 neo on the forehand side and G-1 on the backhand side). I actually really really like Tibhar Fortino Performance. I think I am going to transition to that blade. If you like Tibhar Stratus Power Wood, transitioning to Tibhar Fortino Performance carbon will be pretty easy. I was pleasantly surprised.
I currently own Viscaria and Acoustic carbon but I like Fortino Performance better. For me, touch is very important especially when I used H3 Neo on the forehand side. I like my Tibhar blades basically.
