Well I still have those same problems! Sticks when you need to move, slips when you need it to stay, mostly at inconvenient moments. It will go along fine and then just when you trust it and need it... I always figured it was an old-age problem (both the extension and myself...). The one I had on my 14 never gave me problems, the one on my 18 occasionally causes fits of cussing - both appear to be the same make. We'll see how the one on the 20 works, it also appears to be the same make but it's longer. I always figured uncorking some more money and buying a new one would be the fix, but that eats into beer money!
