arrow length should be 1 inch longer then your DL correct? if so when i get them cut if they are alittle short or alittle long is that ok?

I don't think that's right.

Most people shoot arrows that are shorter than their draw length. I shoot 28" arrows, but my DL is 29.5.

Generally you want your arrow to be about 1 inch ahead of your arrow rest at full draw.

wait a sec, but if they were shorter then wouldnt they come out of the rest?

never mind i looked it up ur right

ok so if it is alittle longer or shorter is it ok though.

If the arrow can be drawn and not pulled off the rest it is long enough. If it sticks out however far past the riser it may not be too long. What is more important is to match the spine to the length and draw weight of the bow, or at least close enough so as to be tuneable.
