Thanks for the help guys. I've narrowed down my choices to the medium "MK" size wader & XL jacket, I figure the L would be a perfectly snug fit but going XL for extra room to put on under garments and more sleeve room for casting. Going to be purchasing them shortly.
I make almost all of my purchases at my local fly shop, But when it comes to these bigger purchase items I find I save a ton more money going online from Still water because they don't charge any shipping over $200 orders internationally. I've bought my GLoomis Dredger GLX spey rod & reel from them in the past without any issues, they are fast professional and would reccomend anyone to use them.
I'm also getting gloves, a bag, hat, wading shirt, including jacket & waders I'm still under what I'd pay for just the jacket and waders here locally. It would be nice to try them on but I think it would kind of a dick move to go into a shop try on their inventory for fit & then purchase them online. I'm confident I have the right sizes now.
