Hi mate!
Way back, I used hard, tacky FH rubbers. G666, G888, H3, etc. Relatively recently I changed (when Tenergy arrived, if I'm honest). After the BTY price hike, I must have tried every tensor going for my FH. I liked Rakza 7 Soft, but M3 was a real eye-opener to me at the time because I found that I could play pretty much any of my FH strokes and be effective - drives, brushes, anything. It was the first time that I felt I could mix my old tacky FH stokes back into my game. It was super-spinny high throw, without loads of the tensor bounciness.
Tensors have improved again tho. I'm using Omega V Pro now, and it's amazing (if a little sensitive to spin). I would happily go back to M3 though. It's cheap (£23 a sheet), lasts a decent length of time, and effective.
I have to agree with you - my FH is probably 100% weird.
Amazing deal from TeesSport on the TBS. It's not like them to ignore the opportunity to empty your bank account. Must have been a slow day!
