In reply to ianstevens:
Thanks Ian. I think that's fair and, to be honest, everyone's take will probably depend on how much they've done on gritstone. Strange to think, but there are folk who never venture much beyond Stanage and Froggatt. Even out of a desire to get people out on the really esoteric stuff though, there was no way I was sending them to the likes of Agden Rocher.
For me, there's a reasonable mix in there between stuff people probably haven't heard of and routes they may have heard of but never bothered to go and do. Even the more popular, starred routes are less frequented than the 'must-do' gritstone ticks. If I were to compare Zapple to another HVS 5b like Flying Buttress Direct for example, it's only got a fraction of the logbook entries on UKC. Maybe "less-travelled lines" would have been a better turn of phrase.
