They're ok but the stud isn't massive to start with its a light racer really. I have a pair for racing and use and old pair for trail running.
What about going for the mudclaw as its got the largest stud, so even when worn it will still out perform most others. But then it will wear really quickly as its softer. You certainly will like the extra grip on the fells.
YD I am meeting with Ken next week to have a chat about things.
There is a plan to PR within Fountains Abbey, I don't think its any secret. As far as I know it just needs someone to step up and be race organiser (set the course, briefing and upload results) as the Hgt Pr guys have done the ground work but don't want to split their time between the two runs. If anyone at TandS would be interested in this I can fb you the details. It would be the most beautiful setting and very popular especially for the PR tourists!
