To Prune or not to Prune Bell Peppers?

I have a couple plants that are ready to start training, and am wondering why I see more branches than were illustrated in my book.. Hydroponic Capsicon Production (sp?) Anyways.. I was thinking that perhaps I should limit myself to 2 main branches instead of letting it run amuck.. but which ones to cut I'm unsure.. perhaps I should try 4 branches. I havent ever had any problems with full blown Bell plants, but want to increase the plants focus on Pepper size and Ripening time.. any help appriciated.
Thanx

pruning the plant wont make it focus on pepper production. its more important to keep the plant regurlarly watered, if you let it dry it will drop its flowers and focus on vegatative growth. good luck!!
