Best Midwest load board

I own one truck and run under my own authority. I have a frameless dump and a hopper trailer and am wondering how the load boards are here in the Midwest? I live in Indiana and currently only have base plates but will get ARP plates soon. I've never used load boards before so was wondering if anyone had any info on them? Or if I should just stay away from them

 

Well I did a search and found a couple sites. I am looking for just hopper and dump work since those are the two trailers I own. I was just wondering how exactly the load board deal works and how successful it is while using it. I don't want to leave my current broker if I'm going to be making less and be less consistent with the boards
