Every rubber tire may work like shit for some of you... That is of one simple reason... Inserts!
The inserts you use is usually the biggest adjustment you can do, and having the right ones is a great advantage. I suggest using Xray or JB wheels with JB/Orion blue inserts...
It's very lightweight foam inserts, so you have to check your weight before running them
Sorex 28, 32 or even 36's allround I would say is the best choice for any track, Orion B's aren't all that bad either, but lacks steering...
