Re: How is Rio Grande different than just over lining?
Learning a lot from this thread.
Diver Dan, I really like your posts on this subject. Is there a way to determine what the ERN of a particular rod is? What about the grain window? Is it just a matter of casting with different lines/different weights to find out how your rod casts with those different lines and weights? Is simply relying on the manufacturers' designations for a particular rod a mistake--i.e., using a 6-wt. line on a 6-wt. rod and assuming that's okay?
Also, I wonder how much of this is subjective--not all people cast the same way, and it seems to me that preferences for particular rods, models of rods, and weights/brands of lines are personal to the person using them.
