Gonna jump in here since I'm a major proponent of proper suspension setup.
I think we're getting to an area were you need to decide what your bike will be used for. Expensive shocks are "cool" but are you really going to need them? On the rear, I say absolutly, go for broke. Just make sure they're tuned for your weight and riding style. On the front, well, this bike is a cruiser. At most, I'd go with upgraded springs and toy with oil weight. Cartridge emulators do work great, but the price out weighs the benefit on this style of bike. Now, if you're goin' Ryca on it, you might consider the higher end upgrades on the front.
This is just the way I see it....your results may vary.
For what it's worth, I'm gonna try the Gazi Hyper Lites on the rear. Fully adjustable, rebuildable, piggyback reservoir, and bitchin' lime green decals!
