trust me, BSP isn't one of the best features...
MOst apps created with bsps pre-patch 4 might not have worked well, if you build one now with P4 things sill be OK for you. BSP's are weird: render weirdly, have weird quirks - if you're using CShop it's much easier to export a .col file and use some code to load the level and sliding collision - you also get lightsmaps that way.
