I have the dobyns fury 733 and it excels at the baits that are printed on its blank. It’s actually one of the best utility “do it all” rods that I’ve ever used for pond hopping and bank beating as well. 

The testing has indicated that most "premium" blanks (I have not tested any "store bought" rods since I build all of mine) do have higher natural frequencies than lower modulus blanks.  This is good news, IMO, since it says we are generally getting what we pay for with blanks.   But there are some surprises when dealing with complete rods and the effects of guide mass/material/design.  It's too complicated to go into in a post like this.  There is one premium blank brand that generally has the highest TNF's of similar blanks by other makers according to my testing and that of a couple other builders.  But keep in mind that I certainly have not tested every blank model nor even all brands. 

 

From what I have seen of store bought rods in repair requests I have to conclude that custom builders offer a superior product with respect to reel seat/grip structural integrity and cork quality.  Plus the entry into the market of numerous  really high quality brands of carbon fiber grips offers options that are generally not available on most store bought rods.
