I’m very new at rod building so take that with a grain of salt but I started out with a CRB turn key kit from mudhole. The components are pretty good imo and the rod is sensitive but the action and power ratings couldn’t be more off. I bought a 6’6” ML and a 6’6” L action rod, both are a power less than what they are listed as. The Light is more of a Med Lite while the ML is a Med action. Both don’t really have a good tip but are decent ned rig rods and finesse worm/skipping rods. They also seem a bit more sensitive than my st Croix mojos which is baffling.
for the money they are great to learn on. Won’t break the bank and if you mess up, you’re not out a lot of money. I also just built on a MHX ML rod and it seems To be on par with the Avid rods with actions similar to the Mojo series.
as for literature and videos, youtube is a great resource and mudhole has a ton of instructional videos. Also the rod building forum website is a great resource as well, but nothing beats hands on experience. The more you do, the better you’ll be
