Nick, saw those wheels on cutters and truthfully, I don't think they're going t give that big an improvement over your current ones.... Personally I'd keep your current wheels and spend the dough on something else, if there's anything else left to mod that is hehe
What's to say you'll get those other wheels and then maybe come across something else and not think about them!? It's never ending! If you've done almost everything and you've really wanted your wheels for ages or always had your heart set on them then go for it... But ask yourself this... Were you planning on buying them later anyways!?
