Thanks Rick, that's pretty much what I was looking for. Might have a look for some Flickr groups dedicated to various well known types, find some sample shots.
JJ - I'd like to give 6x7 a go, but I'm on a limited budget ($1000-1200 or so). I'll have a look around, would've preferred to buy locally, but in a small town I'm not likely to find a 6x7 system for a reasonable price. I'll have a squiz on KEH.com
