I've had pit bull front and rear stands for years and love them with the sportbikes. The first time I tried to use them on my strom though I noticed the rear stand bent the stock plastic fender/mud guard a little too much. The soulution was to install the spools and use those instead of the swingarm pads. Of course you could just chop off a couple inches of the mud guard and use either.
As far as the front stand....I use the standard fork-lift pit bull, I found it works great on the strom just make sure you stay infront of the small extension on the base of the right side fork. My DL is my first suzuki and I believe the extension is just there to allow the space necessary for the type of front axle nut suzuki seems to use on alot of there models. Anyway stay infront of the little doo hicky on the fork base and use the spools and its rock solid.
Oh ya, I also went with the pit-bull spools, 8mm.....same as all the gixxers. good luck.
