Marc,
I do not have much experience or knowledge of Trinidad SR/PRO. I will say that I do like VC-17. It provides a good racing finish when prepared properly, it is very easy to re-apply (in my opinion), it retards growth relatively well, and growth cleans off of it relatively easily. The majority of boats in our area use VC-17. However, we are in fresh water 100% of the time and our water temperatures don't get much above 60/65 degrees. Not sure how that compares to your local conditions.
My two cents for what it's worth.
