Anon, I’m kinda not sure what you want. If I read this correctly, if, you don’t like the height of 147s, which are almost 50 mm, but you do like the height of 148s, which are 52 mm, but may want to move down in board size, ace which are listed at 52 mm you want to have a forged plate lowering the height from 50.5 ish to 51.5.
So you want trucks that are 51-52 mm tall? Royals are close, 50 ish, and better than people think. Indy mids when they come out with a forged plate will be a bit lower, now they are 52mm.
I’ll stand by the notion of 147s with forged plate and a rider being your best option.
I agree with ballin that folks get too caught up in height, but I think that’s because there isn’t another number we can attach to the pop feeling. It probably has more to do with a salad of: axle positioning, height, tail/nose lengths and angles, wb, effective wb, butterflies, board width and length, wheel size, and then our individual body proportions, x memories from back in the day
