RE: Race sails
In plain non painted film, all of the material thickness and weight are used for strength and stability.
In painted/coloured/laminated films, part of what you carry around is just for fancy colours.
One may like one way or the other, but it is not the same thing.
TR-3s rigged on the correct masts (MS SRS 100, Gaastra Ignition) deserve a try. They are different. You don't need to trust my words, so I do not use many; but you can trust the signature under the sails.
