Vision Solos, though probably not as bright as you want, are relatively high in tension: about midway between Dominant and Evah Pirazzi. They seem to lose brilliance much more slowly than Dominants. I have not tried the regular Visions since they have a reputation for being brighter than Dominants. However, I heartily recommend the Solos.
(For the E, I tend to switch between Pirastro Gold Label and Goldbrokat. The former has my favorite tone qualities; the latter I like almost as much, and it is undeniably cheap.)
I really like Rondos for almost every fine instrument I come across. You could try those on a student instrument if you don’t mind the higher price than the more economical sets.
Tonicas are rather good and inexpensive as well, and they are available in fractional sizes should you need them.
I don't understand why you are specifying high-tension strings though. If you have found Dominants to be satisfactory, but just want higher tension, the Dominants are also available in higher-tension (stark) versions.
