In reply to PFWJ: Hi
I am a coach based in North Wales and as well as myself their are a bunch of talented coaches/instructors based in North Wales who would be able to help you out.
I tend to focus on making people climb more efficiently in essence I try to make climbing the same grade routes with less effort, before moving onto pushing your grade. There are various reasons for this but it is my experience that 95% and in 95% of climbers can improve through working on their technique and tactics.
However the real improvement only comes after you put in lots of hard work to make any new techniques and tactics you are taught your default setting. In that I can teach you some things over one or two days, but they will not become ingrained unless you practice them a lot on routes within your ability. As when stressed people often revert to previous ingrained habits be they good or bad.
You can find info on what I do at

I would also recommend the follow guys as they are both good climbers, experienced instructors and coaches. They will all know North Wales really well which does help when coaching this type of thing.
