I prefer 'organic' trails to Mctrails, but they both have their place, particularly for a bit of light relief in the middle of a schlock filled winter.
I'm seeing riders coming through now that seem to have a bias for one or the other – Trail centre riders are generally faster and know how to fly on smooth and groomed stuff, whilst ROW riders seem to have more technical aptitude and line choosing skills.
I was quite surprised when I guided a couple of Cwm Carn DH sessioners round my XC patch – they were happy to ride the big jumps at speeds and heights that would scare the piss right outta me, but I left them for dead down Cheddar rockgarden, which is something I thought they would have liked, being all rad and gnarly.
They got to the bottom and couldn't get over it 'there were rocks everywhere' one said.
err yes. It woke me up to the fact that people are coming to MTB via different routes these days, and there are slightly different skill sets involved.
