I am more leg than torso, so maybe that's why I am always riding frames that are "too small" for me, but fit me just fine with a long seatpost.
A proper fit should recommend a reach, not an ETT. ETT is meaningless for fit if the seat tube angle isn't included. Reach includes the effect of seat tube angle's effect on stem length.
I would start by getting your fit optimized on the Vaya, then use relative reach and stack to estimate your fit on another frame.
