Hey,
Are you racing or cruising? Sailing fully crewed or short handed? Sailing long distance or short distance?
If you are fully crewed, there is no doubt that a spinnaker is the way to go. If you have the budget, then get both a standard spin and an assymetric.
If you are short handed and sailing short distances, then the whisker pole is probably going to be just about as fast. When you consider the time it takes to rig, raise, and douse the chute, the whisker pole would be about even.
I race on a friend's boat with a full crew. We fly a spinnaker as much as possible. I race my boat double-handed with either my son or my daughter. I don't have a spin and won't be buying one anytime soon. A whisker pole is good enough for me in those situations.
If I were cruising for long(er) distances I would probably get a spinnaker. Now, if I am cruising, and the wind is light or from the wrong direction, I'll just motor or motorsail.

I'm interested in your experience on which option is the most effective way of sailing down wind on a boat with a fractional head sail (110 Genoa). I understand there are pro and cons for each. So those with experience with both, I'd appreciate your input. I'd hate to invest in a spinnaker just to find out the a whisker pole on the genoa (or vice a versa) works just as good or better in 80% of your sails. Hunter 30T (1993)
