Would i be wise to take a full face helmet over my regular trail lid?
Is it all graded red black or whatever?
Where are you going? They vary hugely.
Where are you going? Most places aren't graded in that way.
You might die, you might not.
Antur stiniog just spotted the other thread on page one sounds like fun
Better to go overprepared than under; soften up your suspension, get some thicker tires maybe, get your brakes sorted, take some armor if you have it. Full face helmet definitely worth it.
Don't make the mistake of thinking a day's DH riding is just like riding the downhill sections of your local XC trail; it can take a while to get used to the physical exertion especially the arm pain.
Be prepared to have a lot of fun!
I haven't ridden there yet, but it looks quality... I'd fire on the tough grippy tyres and pad up as much as I can pad up- not because it looks mentally difficult, but because it's fast and it looks like there's absolutely nowhere on any of the tracks that would give you a gentle crash.
