I'm 6'3", and don't have the smallest of digit's, and I get on with it just fine. I did take the cord off the cam, but that's my personal preference. I'm even benching my olde style Crolls in favour of it., despite them having very little wear.
I think Starless River have started stocking them now. If you happen to be up this way anytime before you decide/buy, feel free to borrow it and see what you think.
If you want an older style Croll, they still do it in the Industrial/Rope Access, with a different designation (Last time I looked).
