Currently on a 100mm -/+6 Ritchey stem. I originally ride a 120mm on my other bike (55cm) but when I built up my new bike (54cm) I had a 100mm stem that was not being used, so I decided to install that first. Then, when I got fitted by a professional, he said a 100mm will do but is still considered a bit compact.

So here is what I have decided on, to go with a 110mm +/-17 or a 120mm +/-6 or stick with a 100mm but with a +/-17. What would be a smart choice or what will be the most insignificant choice?

thanks
