Have a ball mounted directly to one of the 4 handlebar mount bolts - with a small Ram arm - unit sits right over the handlebar mounts - with direct power to GS - GPS accessory plug.
+++1 on the protapers also.
If you have an older GS like mine - 05 to 08 I think (I have 06 adv) then you might want the Protaper - Raptors which are an ATV bar with a much higher rise than moto bars and a bit less flat like the MX bars.
