I currently have Lee Jr bases and original poles on my Grady 272 Sailfish.  The poles are the originals from the late 90s and need replacement.  (1) I don't want to spend a ton of money and (2) I'd like to get collapsible poles to make transport and storage a little easier.  I've search the interwebs and haven't found an adapter or bushing to make collapsible poles (Lee or other brand) fit the Lee Jr bases.  Has any found a workaround for this or am I stuck purchasing a set of the classic fixed poles from Lee?
