Well, my preference would be for the trigger type fitting. Check out this link
to APS in Annapolis. The first item on the page is a FORESPAR UXP fitting which is what I think you're referring to. While not really necessary for a whisker pole they are great on spin poles when you do end for end jibes. And it really is easier to put on the pole ring on the front of your mast; just shove it up and it clicks in to place.
If you have a piston it becomes a two handed operation.
AFA flying the genny.... you are going to want a topping lift, guy and probably a foreguy, although you *can* get away w/o the foreguy. (also known as the down guy, downF***er, et)
One neat trick is to run a 3rd sheet off the genny and put that in the jaws of the pole. DON'T knot the end of this sheet. Then, IF you have to tack or jibe suddenly you just let the sheet run and use the lazy sheet that you would normally use. Leave the pole completely alone and tidy up afterwards.
You can also furl the sail this way w/o having to fool w/ the pole.
Also, NEVER put the loop from the bowline the sheet is tied on w/ in the jaws of the pole!
