the 5000 series will give you a nice ride.. not as tight as the stock VX or the 9000 series for handling though. When i dial my 9000s down to about the level of the 5000s (4-5 out of 9) the ride gets smoother, but going over bumps, especially when towing just doesnt feel right, too soft.

i usually ride with my 9000s at 7s or 8s
