Guy seems funny and would be a cool guest. He's the one Drew was streaming Halo with for those who aren't aware.
I believe both of them have been on the Bombcast before. At least Drew has. I think it'd be great. They're fairly reserved dudes, but so is Brad some of the time and we love having him on board. That said, I think Drew and Alexis are some of the busiest guys on the site. Drew probably picks up the slack for Vinny while he does the Bombcast and Alexis is hard at work doing the redesign with Dave. So, although I would love to hear either one on the podcast, I'm sure they don't get the opportunity that often.
No offence to the guy (or Drew for that matter) but they're not the most energetic or charismatic of guys to be able to have much of a voice on the bombcast. Jeff and Ryan come to party hard, its their bread and butter.
There has to be a mix. For example, Jeff and Ryan quick looks are usually the most boring, probably because they are so familiar with one another. The quick looks with Dave, Vinny, Drew etc. are the most fun to watch (for me).
