In my opinion try all tyres are the best yet. creepy crawlers lose there grip after a month and the new montys are to wide to fit on most bikes (rims) and i feel would dampen your spring not help it
try alls may cost more but are worth every penny (mine have lasted 3 1/2 months) and are uber grippy. 50 quid a pair is not to bad surly the new montys will cost that
