Oh, in that case...
4x, 3x, pretty much the same. I will say that I found the white Yetis to be less velvety/tacky than the colorful ones. Nothing crazy though. Around these parts the Yeti reigns supreme. I know the local shop has trouble keeping them in stock. I switched over from putting with a Wizard. I was having trouble finding Wizards at Shops, where I could actually feel them. I'd been burned too many times buying Wizards online, and not in person. I eventually found the Yeti, and I slowly but surely made the switch. It was the stability, stiffness, disc feel, and the especially the low profile that sold me.
