Howdy Folks,

I'd like to make up my own Aeroflys, but I don't fully understand their design. Bob posted a pic on this site but I can't make out the details.

Looks like a short section of foam backer rod with a small diameter tube inserted through it lenghwise. True? If so, is the tube glued in place? What about the hook? Does it hang freely behind the foam attached to the leader passing throug the tube? Is the maribou or other material tied directly to the hook like a regular fly?

Also, any tips on materials or color preferences for OlyPen rivers liie the Bogey and Calawah?

Are Aeroflys drifted just like Corkies and Rags?

Thanks for the advice and guidance.
