I went F16 for the versatility. My situation was/is: inland lake sailing most of the time (light air/flat water), buoy racing most of the time, no consistent crew on N5.5SL and young kids getting to the age where they'd enjoy sailing (ages 6 and 8). I was looking for these characteristics in a boat (in no particular order):

1. Lightweight, I need to be able to handle the boat by myself (8 year olds aren't that much help) in the water and out of the water (I weigh 155 lbs dripping wet)
2. Able to single-hand easily (even if racing in an F16 fleet). I'd give up 18 inches in mast height to N5.5 Unis from my N5.5 SL-to-Uni set up.
3. Good light air boat, see local conditions above (no class min weight either).
4. Fast out of the box, I don't have a ton of time to tinker (I'd like to but....)
5. Integrated class legal spinnaker
6. Ability to be "Competitive" at coastal regattas/distance racing from time to time. "Competitive" meaning the boat is potentially quick. Crew ultimately decides "competitive".
7. Production built, my wife wouldn't let me take "her" children on any boat I built.
8. Racing centric atmosphere. I enjoy the post race breakdown/bragging sessions as much as the racing. Being with like minded people is fun.

I had a tough time deciding between the Blade F16 and the Stealth F16. Both seem to be awesome boats, but the Blade has a "local" manufacturing presence lending to an assumption that it will proliferate quicker in the US (can you say Alter Cup boat in '07). Theoretically, parts will be easier to get, etc. I still may try the Stealth rudder system on the Blade .

That about sums it up. Thoughts?
