If you are looking to just get the high E calmed down a bit, try a Knobloch nylon in hard tension. I really like the Ramirez HT Nylon set with, or without, the Carbon G. Every guitar I have used these strings on sounded great, from a $180.00 Lucero, to mid priced models like the many Cordobas I've had, all the way to the three Ramirez I've owned. I think the Ramirez brand high E sounds best, but you can't find just a single string in that brand. You have to buy the whole set. You also might want to try a Hannabach 815 nylon High E.
If you like the sound of carbon, but want it toned down a bit, Dogal Diamanté trebles are quite good. Be sure to order the strong or extra strong tension (they are the same). The Dogal Diamanté are carbon/nylon hybrids. The g string sounds pretty much like nylon, without the tubby sound.
