Graf G500 Pants

[Hammers44 4]

Its time for some new pants! I've been wearing Pro Tacks for ever and want to get into a different type of fit. I've been looking at the Graf 500's in a sz 50 and heard they have a slim fit similar to Tackla pants which I've worn before. I wear a medium in my Pro Tacks and was wondering if anyone knows how much different the Grafs would fit waist wise. Hopefully this all makes sense, long day at work and my brain is fried
