If you were fine with that low (aggressive) stack height on the Lemond, then go for the BH Ultra as the stack is only 5mm taller (run less spacers). Reach is only 4mm longer (run a 5mm shorter stem).

Frame standover on both bikes looks similar; so that's good.

Going to the Strato would be like getting a relaxed fit for you, as it is 29mm taller at the front.
