I believe general consensus is to not do secondary fermentation transfer any more. I stopped transferring to secondary carboys a while ago, and I think giving the yeast extra time to clean itself up in primary will only improve your beer.
I recently made a DIPA with an OG of 1086. I let it ferment in the primary for three weeks, added dry hops to the primary bucket and let it sit another 4 days and then racked to a keg. Simple as that.
Unless you are doing real long term batch conditioning/clarifying, I'd skip the carboy all together.
