I NEVER use secondary carboys except for sour beers or fruit beers. It is not necessary to dry hop in the secondary either. All of the pale ales or IPA's I make ALWAYS get dry hopped in primary after 7 days of fermentation. I then add the hops, give the primary a good swirl to mix the hops with the beer, then let them sit for another 7 days (total of 14) before packaging. If I dry hopped with a lot of hops (4-6 oz) then I will typically crash cool my primary for the last 48 hrs or so to drop out the hops and brighten the beer up a bit before kegging. I have had great results with this and it keeps in line with the KISS method. One less piece of equipment to clean/sanitize, one less chance of infection, less time spent working = more time sitting on my ass drinking my homebrew!
