Nice to meet you Gaz
I got a pair of bocks for christmas too!
Have you checked that your knee bar is in the right place in question of the pain? If it is, it might just be muscles you don't often use adjusting to being used a lot.
The closest groups to you appear to be Sky High and the Derby Bockers
They both have their individual boards with meet info etc. on them.
Nice to meet you as well and I hope you enjoy being a member of the forums
