Ok I have tried gamma livewire pro; ah not so good with tension maintenance, ok for the first hour or so.
tecnifibre multifeel; great multi, soft, comfortable, powerful, and great tension maintenance.
gosen super tek, good multi with feel and power.
now my fav multi now is the superstring voodoo energy. been playing with it for a couple weeks now on different surfaces, clay and hard court, and this has great tension holding ability, the feel is so soft, volleys are so buttery!!! power is definitely there. and i can get loads of spin out of this with out the strings moving all over the place.
need to have more of this in my inventory.
