Rumble 200. You are better off with more power than you think you need, rather than pushing an amp to it's limit. Head over to the Rumble club thread here. You will get good information from @Linnin @Gravedigger Dav and others.
GK is 200 watts too, and has the 12" speaker I like. I'll try them both out, since a combo is apparently going to be a better choice for me.
