Any recommedation for an expert rod builder who can transform my Fenwick Techna GP from a baitcast rod to a spinning rod? Located in NC, but willing to ship.

Richard,

 

I can no doubt do what you’re asking, but it’s likely more economically viable to build from scratch. Email me to discuss.

If you can measure the old rod's CCS numbers you will have a better chance of matching it if you choose to build new.  I would build new.  One can never have too many rods.

I've done it the other way twice and still use one of the rods.  Like DVT and Mick said it's cheaper and easier to build a new rod.
