starting to experiment with fins, small trailer with bigger side, big trailer with smaller side fins

Hi I’ve got 3 sets of futures fins. Basically 1 small, 1 med, and 1 for larger waves. What will a small trailer fin do for me with average size side fins? Will it make the board looser and paddle a litte better with less drag? What about a big trailer fin with small side fins? thx

I use that setup on one of my thruster shortboards… Standard FCS on the sides and a G-1000 trailer. I pull the board out on smaller days… it’s a little looser, a lot of fun when I’m just playing around. I don’t think you can tell any difference on the paddling.
