Have disided to switich from the good old MT43 to Bridgestone TW24 after buying an ex grass track one off of Bob Lewis (it was the last one that nobody wanted)
They seem to last alot longer wich also means the blocks stay sharper as well. After 5 or 6 rides from new I recon it would become the better tyre over the MT43 as the 43 starts to lose its edges.
