Shallow Groove | 8B Boulder problem at Trowbarrow

It seems unlikely that John made the first ascent of this problem.

Dan Varian:

Re shallowgroove i think it's incredibly important to stress that [Aidan Roberts'] is the second ascent of [Ryan Pasquill's] direct. The line John describes in his interview should get written up as a seperate finish after the first move. If vitruvian man has a RH and LH version so should this. Even more so because the RH line has a proven track record of attempts, fails doing moves etc but the LH line only emerged in johns interview and is something entirely different... If Ryans line was easy someone else would've done it in the last 17years. Aidan is super well suited to crimping utter crap whilst standing on a ledge (as is Ryan). Its one of the weirdest hard problems in the world IMO. Literally no extra kudos for a trainers ascent. [1]
