I have a set of Gaz Golds on my track Puma, I'm surprised how comfortable they are.

I would avoid AVOs, I've had a couple of sets on Mk3 Fiestas and a set on an MG ZR160, very solid ride and the rears are prone to clonking. Solid ride may have been down to spring choice but general quality is poor on the low-end AVOs imho.
