My customers are asking me to build custom rods on Shimano Butterfly blanks. Shimano doesn't make their blanks available so I need to build on blanks with the same Power and action.

What blanks would you recommend for;

>6ft-Heavy Power-Medium to Fast Action-50lb Braid

>6ft 6in-Medium Power-Medium to Fast Action-40 to 50lb Braid

>And a similar 7ft blank

Thanks, Don
