Bondy,
You have a fairly good memory, when Worksop started way back then when i was young, We tried allsorts of tyre cominations, Losi Sprints, Proline micoblocks,Schumacher cut spikes [ remember those ] Mini Spikes, Then Mini Pins [ that lasted] [ may be softer motors ] When we were at Scumacher the mini pins were developed fot Astro Turf type tracks.
After all that most soft compound tyres work at Worksop. I now Adam intends trying the GRP in practice next time we are there.
