I went with the 16" Black Steel Antenna from
http://www.autotrucktoys.com/stores/...0292&CATID=413 - truth be told I'd intended on getting the 10" and clicked the other by mistake, didn't notice 'til it arrived. Couldn't be happier with it though as I haven't noticed any loss in reception and I don't have the distraction of 90' of antenna whipping around while I'm driving.
I'd caution you to mask/pad your wrench/tool when you tighten it down as it's easy to gouge the finish.
