Global and Gaucho gut strings

[SoCal10s]

out of all the Global and Gaucho strings which are the most popular strings they carry?? which ones did you like?

I want to order some and I would like some feedback,before I order...

my guess would be blue spiral 16ga, has anyone try the 15ga stuff?

please give some suggestions,I'm thinking of ordering a few sets to try and see which is the best for my purpose.. thanks
