I'm with Kirk on this one. I wouldn't want to break with any of those guys. I want to know the person hosting the break, as well as some of the other guys in the break. I did a few of those breaks with the guys on BlogTV and Breakers.TV and they're just so impersonal. It wasn't enjoyable for me at all, even when I did get nice hits.
Another thing you'll notice when watching these breaks is that a lot of those guys are making money (sometimes even doubling their money) on these breaks. I don't like that. If the host makes enough just to cover their team, no big deal, but there are a lot of those guys making a LOT more money than that and I just don't want to deal with those guys. I'd prefer to deal with guys who don't make any money at all, not even enough to cover their spot. Hosting a break is fun, at least for me. It's not some job that I want to pay anyone to do. Again, this all just goes back to knowing, and trusting, the break host.
Just like Kirk, I like to stick with the "group" breaks where you're breaking with the same guys monthly. I'd recommend checking out any of the monthly groups here at TCZ or over at TCC. They're all hosted by top notch guys who don't treat it like a job, but rather as a hobby. I haven't been around the other sites enough to vouch for any of their hosts.
