I'm wondering what the best weight for a gi would be. I've been looking at this: http://www.ebay.com/itm/New-Century-Martial-Arts-Karate-Gi-Free-White-Belt-Size-5-/141281362248?pt=LH_DefaultDomain_0&hash=item20e5068148 Perfect price for me. I think this is a 6 oz (lightweight?) and there are a few 8oz for about the same price. Is it better to go with the 8 or 6oz for a beginner? I'm just worried if I go 8oz it'll hinder me.
