Definitely a great way to sort out the front end a little for street riding. I'm 180lbs without gear, and found the stock forks on the 796 extremely soft from the factory. Could be based on the fact that they were originally designed for the 696, and then "bolted" to the 796 to keep costs down.
I've used Racetech on previous bikes/suspensions, and have nothing but good things to say about them. It's not perfect, since the damping is setup for the stock spring rate, which you can only somewhat change by oil weight, but is plenty good for the street.
I decided to go the fork replacement route, and ended up finding a good used pair of M1100 forks (stock not the Ohlins on the S) since I take the bike to track days. Best investment I've done on the bike. Cost was roughly $500, but well worth it in my opinion, as the front is now adjustable and rides extremely well. For track days, the adjustability is a big plus, but for the street, you basically set it for yourself and forget it, so the Racetech springs are a good way to go.
Either way, if you do any kind of aggressive riding (basically anything more than commuting), you should definitely consider a fork upgrade first.
