i have nothing to contribute that will help OP.
but I wonder how much weight is saved vs. a CF fork with AL-steerer? I have an Al steerer and first wished I'd rather have full carbon to save weight, but reading all this I'm glad i have an AL steerer.
I fiddled with the bar height many times (and ended up higher now than after the first year of riding). Had I followed the recommendation to not have any spacers above, I would have had a too short steerer now. Keep in mind finding the correct fit can take forever since the body also adapts and changes. Having future flexibility is important, not only for resale.
