I have been trying to define the fin and rudder shape today and I have two rudders (on the same fin) that I am considering. I thought I wanted something like the S-1T, a shape that isn't really round but more of a stock (small) rudder extended back a couple of inches. The other shape I created is more round and similar to rudders I have made in the past. BTW, the fin has been altered as well -- 1" narrower and about .25" taller with the same LE angle.
Another BTW; I have 5" of added tail moment so my tail volumes would be larger than the stock S-1S.
Tell me what looks better to your eyes (you too Grassroots!) or even that neither one looks right;
