I recall you was entered into my PIF and should you have won I would have posted the blades to you! P.congrats. but also geez i hope someone does one that USA can enter sometime.
Edit..... Larger things than blades though could start costing more than the goods in the PIF are worth so this is the reason why most UK based PIF's are only open to the UK.
I'm sure one of your countrymen will be putting somthing up for PIF at some point. P.
