New Map Woes

I've been working on a new map. Its kind of a port of the popular Counter-Strike breakfloor map. I'm having trouble with the compiling of all the blocks. I don't think Hammer can handle all of the gibs (Broken parts) that the blocks are going to make when broken. So I'm trying to lower the amount of broken block parts.

Also, I'm debating on whether or not to have it where its only one class, like Scouts only. Because when play testing some early test maps, a solider or a heavy and dominate the map.
