For the Cross Check riders out there what size do you ride and what are your measurements?

I'm 5' 4" and have longer legs than torso. Right now I ride a mixte style road bike so I'm not really sure how long my TT should be. My partner has a 50cm road bike that I sometimes ride on which is fine if just cruising around town, but I want to eventually race cross so I'm thinking I'll need a smaller size. To make it easier to dismount.

I tried a 46cm Long Haul Trucker when I was shopping around one day and felt a bit cramped on it, but the cross check is a whole different bike.

I was thinking I'd like the smaller size and if I feel cramped I could always switch to a longer stem to compensate.

Any advice would be awesome!

I've also been looking at the Kona Jake which has IMO a better variety of sizes, but I want to be able to use the bike for all things. Road riding, light trails, cyclocross, and light touring.
