I'm either dropping 600 on a sierra, or anothor 140 on a zulu (on sale now at sportys for 740.....EEKS...either one is butt load of money, but I gotta have it quiet....and comfortable. Please, anyone with 1st hand experience in either, or have already done the proving, please reply. If the thread is already here, show me the way. I've searched and didn't really come up with nothing like I'm after. Thank you, DM
