Any issues with goruck plates wearing out nylon. Back in the day I put two 25# plates in the radio pocket of an Alice pack. They rubbed and burned through the nylon where they contacted the frame.
Nope. And without checking, I'm over 1500 logged miles with that GR1 since mid/late 2014.
I haven't had to send anything back but they'll fix them for free if you ever do.
Edit: For training, the "Rucker" will do everything you need and saves weight and cost. They don't look horrible or tooooo tactical or too mountain man either. Nice to train without having to wear a big ass stone glacier filled with hunting gear around town.
My dad wears his walking around Evanston, IL almost every day with 30 lbs.
