hi scorpnox and greigco, i play in Belgium too (1ste prov) and i used to play a Genius sound (the softest genius) in 2mm on my fh, i now play a evolution FX-P and i think it is comparable to the genius sound but has slightly less catapult, more linear speed, more control , about same amount of spin.
i do believe the el-p would be better for fh because a little harder and better to finish the points
i find the fx-p lacking some finishing power ! the fx-p hardness is about like a sriver fx i would guess, not butter soft, very good blocking and pushing, sometimes makes me think of a tackiness d with more speed
i would really like to try the el-p next time !
oh and durability after 1 month of play seems really very good, clearly better than genius sound
