Re: I ordered my blank -
if you've used batson in the past then you might be aware that they have guide spacing charts at their web site. look for Guide Spacing Chart 1.
if you order your guides from a vendor which specializes in selling to hobbyists and pros who wrap rods, then you generally receive extra customer service. tell them what you're wrapping and they can recommend the sizes. i have heard the big places don't usually offer this service. i usually use places like gregs custom rods, hook and hackle, custom tackle supply, utmost enterprises, etc etc. and i always get great service from these places among a few select others.
good luck! it can be fun.
