I use T.M. rac os2s, and honestly I absolutely love them. They are my second set of irons, and I was instantly a better ball striker. They are also an excellent value. You can get them for 330.00 brand new online... (am i allowed to name websites on this forum? I'm new, i don't know the rules yet...)
I have them with stiff flex steel shafts, as I am also a pretty fast swinger. My 9 iron carry is 150 yards, 4 iron is 210. You are correct that these irons hit a high ball, they do so for me even though I am a sweeper and don't take much of a divot even with short irons. Any short to mid iron is almost certain to stop for me on all but the fastest greens due to the high trajectory. Pitching wedges spin back a couple feet quite often. But honestly, I don't think you're going to have issues with ballooning shots or a loss of distance with these irons, unless you are teeing the ball way too high, or know something i don't.
I think these are well worth looking into. They may be a few years older, but they are really great irons. I have not met anyone yet who tried them and did not like them (my best golfing buddy also uses them, and they are the rental clubs at my local course).
As far as personal preference on offset and set up goes, i can't help you there, but i will say that confidence at address is an issue for me as well and I like they way these set up and look.
