I think Larry(?) Batson http://www.batsonenterprises.com/index.html
makes OEM blanks for a lot of small brands and custom builders.
I have heard a lot of good things about Batson's Rainshadow blanks.
The next blank I buy will probably be a Rainshadow. You can't beat
the price.

Custom Tackle Supply has last years Rainshadown blanks at 50%
off. I've never built one, but like you heard great things
about the blank. I decided to buy a few and build up a couple
rods for my niece and nephew and perhaps a travel rod for
myself. At roughly 16 a blank, it's hard to beat right now!

Incidently, Dan Craft is a retailer for Batson blanks, and he has
his own line of blanks. Don't know who actually makes them, but
I have heard rave reviews for the Sig. IV and V lines. I am
plugging Dan because I have done business with him before and
found him to be a nice guy who provides great service.

I recently purchased a Dan Craft Sig V blank. Haven't built it
yet, but this blank is incredibly light. Dan is very helpful
and will get you started in the right direction. I've never
heard a bad thing about the Sig V blanks and it appears this is
currently one of the best bang for the bucks on the market.

Warren, a good source of info on rod building can be found at:
http://www.rodbuilding.org/ A number of sites have rod
building step by step instructions as well. Let me know if you
are looking for something in particular.
