Potting up peppers

[jmsieglaff]

So I start my pepper seeds fairly densely and then thin by potting up. In the past I've used 4" square plastic containers--the same I use for my tomatoes. I'm wondering if this is overkill for peppers? Should I just use my deep cell 4-packs? My peppers (Yummy, King of the North, and Serrano) are just getting first true leaves and are usually planted out ~May 20. I grow them relatively cool so they don't grow overly fast. Any comments?
