I was wondering if any of you have ever tried or heared about RENN discs?
As I can see from their website ( [url]www.rennmultisport.com[/url] ), they have 3 models : 575, Kaiser and Madeira. The prices are not so bad compared to ZIPP, and they don't seem too heavy neither (1060g for Madeira).
Also, is the Madeira model a really smarter choice, considering it's 250$ more expensive than the 575 for a 140g weight reduction and 6% more rigidity?
I'm looking for the best bang for the buck... ya know! :D
