I'd just go ahead and buy some Gold Tip Traditionals. I think you said your draw length is 30"? So your arrow length will be like 31", I assume. 3555's might work, but I bet you wind up with 5575's and a little extra tip weight, because I think the 3555's might be spined too soft. See if you can get your hands on a couple of 'em inboth sizes and try them out before choosing.

Or do the samewith the CX Heritages JimPic recommends. Same difference.
