My take:
Summer – I miss the old rooty, rocky, Bristol-ness. Bring back the old trails.
Winter – interesting, challenging, bmx-y, not remotely my type of trail, dry, gloop-free trails. Superb.
I’ve had 20 years enjoying the old stuff, I could easily descend into grumpy old man “it was better in my day” nonsense, but overall – it’s new, it’s different, it requires the acquisition of new riding skills, it demonstrates a commitment to mountain biking for Bristol – bring it on.
