Adventure
Go for the Adventure, i have had the standard Gs, and am now the proud owner of a Silver Adventure, the only thing better than the ADV is the colour ( period ) the adventure corners tighter, and is faster than the standard GS due to the low first gear you get with the overland package, this as been confirmed to me by others in the Gs club and also by other guys not associated with this club, the seat is also better, having owned both the high and low seat for the Adventure, i went with the high version.....there seems to be a lot of guys who change the make of seats on the standard Gs IE sergent, corbin wunderlich and tourateck, are just a few, if the seats were much better, i ask why change,
The choice between a Adventure and a Standard Gs is purely a personal thing, and one thing that will be discussed many times more on this board, but i believe go with what srikes you as the right chice for you, and not what someone else professis to be set in stone.
