Those numbers are the stiffness/spine of the arrow, it depends on your DL,DW,arrow length,cam style, and speed of your bow as to which spine you should use.
Those number on the arrow sometimes, but not always refer to the static spine(stiffness) of the arrow. You have to look in the manufacturer specification of the arrow you are consdiering to find out the spine rating of the arrow. Sometimes the number is just a model number used by the manufacturer to differentiate between arrows.I was looking around at some websites and noticed that arrows come in different sizes. i saw two , 350, and 400. whats the difference between the two?
When ordering arrows online, they come full length(31 inches typically) meaning you would need to take them to someone to have them cut to your desired arrow length.The DL is 28 or 29 and DW is 60lbs. that would be really helpful. What arrows do you guys use? and when u order arrows online do they come ready to shoot or what else must you buy for them to make them usable?
