I have the same sail in the same size.
After my first outings, only managed three sessions on it before proper winter arrived here in Sweden, I must say that I really like it. I have also used the previous Tricera (4.7) a few times, and feel that this is a fairly big improvement.
It has quite a bit more shape in the bottom of the sail, has more power and remains stable for a three-batten design. There clearly is more tension in the foil, which I think is a good thing for the sail to maintain its shape better. If there was one area where I felt that the previous Tricera could do better, then it was power and this is now improved. It does not offer the same top-end control as the BlackTip, but better than expected.
I have also used the "bench mark" three batten sail, HSM KS3, a few times and they are actually quite different. The KS3 offers more continuous power and just pulls like a train, still very good on a wave as you'd expect. I'd also say that the KS3 is more stable in the upper range. The Tricera requires a bit more work, but on the other hand I think that it feels lighter and more neutral when sailing. I also prefer the feedback and feel of the Tricera, even if the KS3 remains a sail that I remain very impressed by in how it combines power with manoeuvrability.
I think that this is a very good float-n-ride sail and as a result I am yet to use my new BlackTip 5.3... Oh, and the Tricera 5.0 sits very nicely above the BlackTip 4.7, even if they are close in size.
Would be nice to read more about what you think of the Tricera and if you've tried different settings. I rig mine on the RDM 10 mast.
A couple of pictures of my Tricera in yellow (very yellow...).
