I've heard of people using various furniture waxes to achieve particular looks, such as a high luster shine, or a deep satin. Also, I've seen some very fine looking, satin finish that was done with the Birchwood Casey 'stock sheen and conditioner'.
I would let the tung oil dry completely and see how it looks before you decide what route to go, I redid my 91/30 with BLO and then 1 coat of Birchwood Casey Tru Oil, which is basically BLO with some other stuff in it, it looked good when I was done, and after about a week of 'curing' it looked even better, and I decided not to wax or anything.
