I agree with the dry hop and then cold crash method.
On an unrelated topic, but nonetheless IMPORTANT...
I would strongly advise against using one of those carboy handles on a full carboy. A full carboy can weigh upwards of 50# and that amount of stress on the neck of the carboy can be an invitation for disaster.
I personally learned this about 2 yrs ago on the VERY FIRST time that I used one of those handles.
Thankfully, it was only filled with 5gallons of water AND
more thankful that I was moving forwards when the neck snapped and the carboy hit the garage floor and shattered!
Glass shards in every direction and complicated by the force of rushing water, I was still finding pieces of carboy months later underneath cabinets and tool boxes.
Just my .02, but I would hate to see a fellow human gashed wide open by shattering carboy glass.

Do not mistake my kindness for weakness. I am kind to everyone, but when someone is unkind to me, weak is not what you will remember about me.
