To pinch or not to pinch

[lurley]

My peppers that were started earliest have reached at least 6 inches tall and are in 4 inch pots after about 5 weeks. Here in zone 5b I don't plant out until mid May. So with eight more weeks of growing to go my question is this... should I pinch out the growing tip on my peppers? Will this make them get bushier like other kinds of plants, so they don't get too tall before plant out? Good idea or bad idea?
