Well, they currently only have Aquila Red tenor sets at Baan here in Bangkok. I know I can always order overseas, but I thought if the tenors work well on a concert, I'll just buy more tenor sets.
I imagine it being like one bad monkey said, somewhat loose tension, but I don't mind tuning up a bit when playing solo. Still, if anybody has had a similar experience, (tenor strings on a concert) I'd like to hear about it.
