As Kevin guessed - yes, there are a couple of tweaks to make Chrome the default browser. There's the "old" standby, BrowserChanger, which has been updated to allow for making Chrome the default. This free tweak allows you to select from several browsers, not just Chrome. In addition, it comes with an SBSettings toggle, so you can turn off the tweak (and thus make Safari the default again ... temporarily).
The newest browser tweak is called "Browser Chooser." This one is only to set Chrome as the default. As with Browser Changer, this one is free, also. It's by the developer Ryan Petrich and this tweak is only available on his beta repo (rpetri.ch/repo).
Those two, along with the one you listed, are the only ones I am aware of. Maybe someone else can think of one I may have missed. Otherwise - that's it. They are both good tweaks, it's just up to you to decide which one you want to use.
