Thank you all, I appreciate the help. 
Celticleather, I'm just outside of Brighton and try to go into London as little as possible. I would make an exception to go somewhere to actually feel the leather because you're right, I'm hankering after touching it and getting a feel for it. I have no idea what sort of thickness I would need for that pouch.  
I have come across the leprovo website but find it rather difficult to navigate. They do seem to have a most comprehensive range. 
Dirtclod, yes I do agree, they maybe are a bit overrated, however, I do like their aesthetics and materials.  They have a good feel for the way a product looks and will age. Whilst perhaps not being the most complicated of products, to me they do look very nice - doesn't make me want to drop $100+ for a small pouch though.  
Also, as an aside, how do I change the flag underneath my name  
Many thanksMatt
