Questions to ask. Am I trailering alot. Am I the only "sailor" on the boat if things get interesting? Am I mobile enough to go forward for those sail changes? Just to throw out a few.

Those are the questions we pondered.
Our boat came with a CDI furler, but I had originally considered removing it in favour of 3 hank on sails.
We currently have marina slip on on a very large lake (9500 sq miles) that is shallow (mean of 40 feet).
On our C22, with narrow side decks, I'm not a fan of going forward in the waves that a shallow body of water of that size can produce when the waves start breaking. Especially if I have less experienced crew.
This huge lake can be really ugly due to its depth and it's ability to spawn cells out of a perfectly blue sky a 1/2 mile away.
If we were sailing on a different body of water, I'd likely switch to hanks, but for now the furler is working well.
Once rigging changes are complete, all our controls will be in the cockpit. Sure, trim would be better with hank on, but I don't race this boat.
Trailering isn't a big issue IMO. not much hassle to raise the mast and rig, even with the CDI.
YMMV and it all boils down to how you use the boat, crew abilities, and where/how you sail.
