Tusa SF-15 or Smoke on the water. I have tried both. The smoke on the water was too stiff for me, I got rid of it. I have 3 pairs of SF-15. and 1 SF-8 black. The black SF-15/8 has a stiffer compound then the Yellow, Red, Blue, or White. I either use the SF-15 black or Apollo splits.
And No cave/wreck/Tech with splits period.
