In reply to smile youve won:
If you're just looking for something to haul a load of gear on non-technical approaches, you don't really need something that's specifically marketed as a "climbing pack". That generally marks out features that make the pack better for actually climbing with, which you don't seem to be interested in based on your post. You probably just want a rucksack around about 40 litres that's up to holding a decent bit of weight and sits comfortably and stably on your back. Lots of packs will meet that criteria well and, in my opinion, how well it fits you is the most crucial aspect.
For what it's worth, my general cragging pack for years now has been an Osprey Talon 42. It's a good size and shape to swallow all sorts of gear well, compresses different size loads easily, carries comfortably and has been pretty bombproof for me for about a decade. I also find the external stretch pockets really handy for gear I've run out of space for, am chucking in at the last minute, or want quickly accessible. You won't find useful external pockets like that on packs aimed at climbing but they're dead handy for a cragging pack.
Some manufacturers like DMM or Black Diamond now make cragging packs specifically designed for hauling your gear to crags with extra features aimed at organising your gear and accessing it easily. Can't comment on those because I haven't tried them but if you want something with a specialist label attached, that might be more relevant to your needs than packs like the Mutant that are designed for being on your back while you climb.
Edit: And I forgot that a top compression strap under the lid for attaching a rope is invaluable. You can normally use the lid to hold a rope on but an adjustable strap is easier and more secure.
