Burnout

Hey folks, I wonder if anyone with experience with the newer steel Cinelli Vigorelli track frame might be able to offer me some comparative information.

I have an aluminum Vigorelli in a 52 and I feel like the bike fits me well and was well set up for my physique without any elaborate efforts. I am 67.5cm tall with a slightly short inseam for a guy: 75.5.

I am interested building a steel Vigorelli, and beyond the more relaxed geo. already baked into the "Crit" intent that Cinelli designed the frame around, I am also a bit vexed by the sizing differences between the alum. and the steel - and before saying any more I understand that this is kind of apples and oranges here nevertheless:

The steel frames size at 50cm, then 53cm, etc. I am leaning toward a 50cm, but could almost imagine the 53 working, though in all important measurements it is bigger than my 52 aluminum bike. I have read and looked at all the numbres for the Aluminum (which I am familar with) and the steel in both possible sizes. Part of me is am honestly wondering whether the steel may just not be a good fit for me at either 50 or 53 - I can certainly ride either one, but I don't want to make heroic compensatory adjustments in the form of no post/skying seat or crazy long stem/stubby, etc. I can't get next to a built up 50 or 53 in aluminum since I no longer live in Chi/NYC as I did for years.

I wonder if there is anyone here who is some where in the neighborhood of my height/inseam who has rode/rides a new steel Vigorelli in either of the referenced sizes and who might offer some perspective. Any input would be really appreciated. Looking at the measurements my gut tell me to go for the 50, but that seems counter-intuitive, given that the 53 is closer by designation.

Thanks a lot.
