Hi,
After reading all the opinions on this subject (some good and some bad} i have this to say. Trials riding is a cheap sport after you have spent all your cash on the big bits, as in the bike, boots, helmet, etc then i think you are trying to rob Peter to pay Paul and this will only put the price up some where else for the riders. If you want to save a tenner then try a different sport like window shopping.
