Well, gut's playing charateristics dominated in this hybrid set up for a while. Very lively feel with just added control of polys. But after 20-30 hours of so, the string bed is rapidly firming up. I guess it's the poly losing resiliency. Once poly loses resiliency, this set up seems to become nearly powerless. My setup (Head FXP Prestige MP, 18x20) makes string bed last very long. I want the playability of this hybrid setup last a bit longer. Anybody tried to remedy this problem ? My set up is Bab Tonic + Luxilon BB, Legend + CF. There's MOJO setup but I really like the added control via poly on gut mains.
