On that boat I would do a main only. There is one fellow with a San Juan 26, that regularly comes in to our marina under main alone right to his dock. Another fellow with an Etchels also comes in under main alone.
For me, I would do the main no matter what I was sailing, as I personally find that sail to be easier to finesse the boat if you will speed wise etc with the traveler/main sheet system vs the sheets etc on a jib. I used to dock a 12' boat I sailed that way to, under main, either dropping the jib, or letting it luff on the way in.
She drives me boat,
I drives me dinghy!
