I have been reading here that my TiMO will go dead after 20 hours of play. That's about 2-3 weeks for me max. Now I do have it on the mains only, I do not know if that makes a difference or not. I want a lot of control, and I get it with the TiMO/Gosen combo. The Gosen seems to work quite well on the crosses. I guess Polys just do not last that long if you hit it hard. I'd love to find something that has real nice control and doesn't cost that much...maybe all Gosen? :-?
