I am looking for a new modern steel frame to build up. I'm deciding between Wraith Hustle (top of my budget):

The Hustle | Wraith Fabrication

and Soma Smoothie (not as nice but half the price)

Smoothie | SOMA Fabrications
.

I'm about 5 10 1/2 with cycling inseem of 33" I used the compative fit calculator and got this

Seat Tube Range c–c:
Seat Tube Range c–t:
Top Tube Length:
Stem Length:
BB–Saddle Position:
Saddle Handlebar:
Saddle Setback: 54.3 - 54.8 cm
56 - 56.5 cm
54.7 - 55.1 cm
11.2 - 11.8 cm
71.8 - 73.8 cm
53.7 - 54.3 cm
5.6 - 6 cm



For frame of reference I have had a CAAD frame in both 54 and 56 and both "fit"

. I like a somewhat aggressive fit and found the 54 with 120mm stem to work very well. 56 with shorter stem was comfortable but probably as big as I would go. I have owned other bikes including bigger frames closer to 57-58 and felt they were way too big. I also have a traditional steel road bike in 55x55 which fits pretty well.

I really like the idea of the Wraith bike as a really nice steel frame that I could have the rest of my life but the fact that they have only 4 sizes and big jump from M to M/L scares me. The M with 540mm top tube seems like it would be pushing my limit on aggressive side. The M/L has a 565mm top tube and I've had a couple of bikes that size that felt like I was driving a Cadillac The 578mm seat tube on the M/L also makes me think I would need the saddle pretty low. But the Wraith seems to have tall head tubes for the size and I know that can shorten the top tube so maybe the M/L reach would feel closer to a 55 cm top tube? And more importantly would the M with 54 cm top tube feel more like a 52? Any thoughts? Unfortunately these are both sold as frames only so I can't really test ride. The Soma has many more small size increments and I think the 54 Soma Smoothie would fit close to a 54 CAAD and 56 would fit close to 56 CAAD.
