Just treat those lines at swinley like a slightly inclined pump trail, no need to crank like a bastard just pump and scrub as required, you’ll get faster the more you ride and learn them…
I think what most people get wrong is braking points and input; hauling on the anchors too hard halfway through a berm is an indicator that you probably should have scrubbed a little bit of speed off 2 corners back, most mistakes are made 15-30Ft further back up the trail from the actual point of impact…
Your new tactic of “feet up” relaxed single track riding will probably actually make you quicker over time than a frenzied attack on each run… Have fun…
