Between a Ritchey Pro Carbon Matrix Stem 4Axis44 and a PRO PLT Carbon Composite Stem. I need to go from a 120 mm to a 110 mm. I thought id go with a carbon wrapped alloy stem for the added stiffness, and cosmetic preference. Do any of you guys have one of these stems or maybe experience with the companies? I can find both stems around 40% off. I can get the PRO about $10 cheaper. What are your thoughts?
