There is a foam roller that is foam with a hard PVC core, I think you can grab it over at perform better.
I like the one I got over at EliteFTS, ok my broither got it for me as a Christmas present a year ago but it's still working and I'm usually ~180-195 and I use it pretty regularly too.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
