How do you know you need it forward? Often that throws more weight on the hands and can lead to hand fatigue or wrist strain - maybe even carpal tunnel. Is it that you feel you have too long a reach to the handlebars? It might be that a better fix is to raise them a bit or get a shorter stem. Or maybe the whole bike is too big and thus the top tube is too long. "Rod" sounds male, but if you were female, you might need a woman specific bike frame, since woman have longer legs and shorter arms relative to a similar-sized male.
