Just after a bit of advise please. Thinking about purchasing a raw pair of busters but my only niggle is how slim they are. Looking at the measurements they don't seem much different to the 634S but from reading comments they obviously are, just how much slimmer though? I'm currently loving a pair of 634S in a 31 but at 6ft with skinny legs are the busters going to make my legs look like a pair of drain pipes?
Cheers in advance

received my 634s on Tuesday, first thought, amazing quality.  Totally agree that for such a heavy weight the comfort and feel of them is amazing.  My true waist is 32, i opted to size down 1 which im glad i did.  Only ever so slightly snug on the waist at the moment but know they will be perfect after a little give. 
The only thing that did surprise me is how slim they are for a straight cut, i would not get away with any of the slim cuts from IH. 
Overall could not be more pleased, know they will last a long long time

finally committed and bought the 634s
cant wait

cheers everyone

dont want them skinny as my legs are bean poles ;D.  gonna go for 31
thanks for the advice

right, first post so go easy.  Looking to get some 634s but from what i have read still not sure if to size down 1 or 2 sizes from true waist which is 32.  Im thinking 31 would be fine, am i right?

cheers
