Indy Ti are the least favorite of any modern truck I've tried. I don't think normal forged would be any better. You're right they make the board just sound weird, the turn is just subpar for an Indy, and I didn't care for the pop of 'em.
These Stage 4 I definitely don't have high hopes for. I've got a deck in the closet that I'd normally have as a transition setup so I figured that I would put them on there and see how it goes. I don't ride super loose so what I am hoping for is a more controllable Ace. I liked my Ace a lot on transition at first, but would often be cranking the bushings. I swapped to hards at one point and then was like "I'm trying to create a different truck", my friend introduced me to modern Thunders, and eventually I became Awake.
