First off hate to hear of injuries so hope all mend quickly.
I did Llandelga for the 1st time last Sunday, I found the trails loads of fun but they just flowed so nice I was compelled to ride them fast and this brings home how careful you need to be, would of hurt bigtime to come off on that surface at speed but I have reasonable ability and experience knowing where to be cautious.
Saying that from experience I’ve been involved in and witnessed some scary looking falls and walked away relatively unscathed, then minor falls have caused serious injury. The worst being over kinver freeride, there are some big jumps/drops/gaps and some small ones, one time this dude hit this real small jump and snapped the big bone in the top of his leg (forget what its called).
