The Tour Solid is a weaker version of the Zero. A weaker cover and a weaker core, but for me very similar motions. The Zero will handle heavier volumes up front due to the stronger cover as well. My Tour solid is more of a bench piece. Predictable and continuous. I think the Asylum will me stonger in the mids. Layouts and your style may yield a different result. I am also 20 mph at release and 450 plus rev rate.
The reign of power is sooner than the tour solid. The reign on has the same length with more angle for me. The cam core has a much higher rg than the tour series cores. I feel you will go Asylum, Zero, Tour solid, Hyroad. Thats some great choices to have in your bag!
