looks like my spring choise is wildly off...
Brian, forgot to say thanks for the hints, I'll try your suggestion, with 30 wt, as my 27.5 is like water, it's about 7 years old...
Dan, I'm still playing with touring cars too, and 1/12th... I reckon it's all halped my off road, as i could never make a regional B beforehand...
Olly's still about, I've been golfing with him recently, i'll remember you to him next time i see him...
