No idea how tall you are dogfish but very few people have a true 30" draw unless they are over 6,3" or have ape length arms. Stretch your arms out full length and measure your wing span from middle finger to middle finger and decide that length by 2.5. That is your true DL. Adjust your bow for this DL other wise your force curve will be off because your are either short drawing or drawing all the way to the wall . Either will affect accuracy or speed/power. IMHO the vast majority of bicycle bow shooters do not know how to size or tune a bow. Also shoot the heaviest arrows you can tune.
