Tech/Mechs: Opinions on Speedplay pedals?

I've been having some re-occurring knee and lower leg issues for the past couple years as I have re-discovered road riding. While physiotherapy has helped (the glutes are firing much better now apparently), a few friends have suggested switching to Speedplay pedals due to the greater float (15-degrees as compared to my Shimano 105 pedals with 5-degree float). I have questions for the PdC cognoscenti:

1- any experience and opinions on Speedplay pedals?

2- cleat wear issues? My LBS (www.bikebarn.ca), who are awesome, are luke-warm on the pedals due to high wear rates on the cleats. Any thoughts?

3- Zero vs. Light Action models? The price is apparently the same at the LBS. Any opinions on which way to go?

Thanks in advance for your sage advice!
