SVonhof I kinda figured the business was gone. I think I tried to look up the website to no avail. I have seen them on eBay. Even thought of picking up a Duet for my kid, but don't really wanna spend $100+ on a putter for the kid right now... at least not until we get settled next month and I find a decent job.
For the record, the aluminum weights are ~17g, the stainless are ~50g, and the tungsten are ~100g.
