First of all if you are just a player I dont think you have any risk outside of how stable your book is. If there are other activities involved then I wouldnt deal with guys that DONT have their own agents in the US. So ticket writing head shops carry less risks from that aspect.
Your main risk is the stability of your BM. If you tag him for $50k one week will you get paid? Or will the phone be dead and the office moved across town? We see a lot of midnight riders here in CR... credit midnight riders.
Personally, and not because they are sponsors here, I think you are safer and would be happier long term in books like CRIS and Pinnacle.
