I'm after advice please. My current selected guidebook for Scottish rock climbing is the 1990 version by Kevin Howett (I also have the even older Hamish MacInnes one!). I'm looking to update for occasional trips north of the border.
There seem to be two current selected guide options: the SMC/SMT single volume Scottish Rock Climbs, 2005, by Andy Nisbet or the two volume Pesda Press offering by Gary Latter (North 2009 and South 2017).
Which option would those in the know advise? I'm predominantly into easier and middle grade mountain routes, with a vague ambition to tick Classic Rock in my 70's along the way.
The fact that the Gary Latter option is twice the price (two books) is not an overriding consideration if I'll get better value that way. I don't think I'll be visiting often enough though to justify the cost of all the definitive guides.
Many thanks indeed.
Martin
