Personally, though I'm definitely an old-skool tech gnar rider, I think BP could do with some dumbing down though not at the points everyone else is referring to. I think the worst bit is the rooty section followed by the punchy climb just east of the Pipeline exit. I find it impossible to get any flow along that 200 metres (?) section. Once up that little climb, heading to Mtn Hwy flows really nicely and even the descent to the water fountain, whilst challenging, should be doable by a confident intermediate and, as others have pointed out, the very techy sections are short and walking them won't add much time to a ride
It would be awesome to extend the bridgework at the bottom of Pipeline to cover all that stuff.
There's nothing better than an Orangina after cheating death with Digger.
