I'm a new 5-Spot owner/operator and I have a question. Are there any riders out there who weigh close to 225 and have a Romic Shock? If so, do you think I can get a way with a 550lb sping? I tried a 650lb spring but it seems stiff. Next I bought a 600lb Ti spring. Now I"m wondering if a 550lb spring might work. Thanks in advance for the feedback.
