I'm almost exactly your size and weight.
I really like my Aerotech Gel Touring Bib shorts in 2XL. They have mesh pockets on each leg which are kind of meh but sometimes handy. The chamois is nice. If they make it without the pockets,.I'm getting another pair.
I also have a pair of Black Bibs Navy Ultimate shorts in 2XL. IMHO, they're definitely not as nice as my Aerotechs and the straps seem short. The chamois feels good at first, but it doesn't last. After I bought them, they announced their Ultimate bibs now have an extended strap option.
