Another thing you could also do is call around to local people who give drum lessons and see if they have the setup you are looking to try. Explain what you want to do, and maybe even bring your kit with you if you find someone who uses a trigger io also. Might cost you the price of a lesson, but would save you a 45 minute drive to Guitar Center.
As a last resort you could always take advantage of Guitar Centers 30 day "Satisfaction Guarantee" if you are dead set on getting a new brain. 15% restocking fee if you wanna return the item, don't know if it applies to exchanges though. At least that way you have a few weeks to try it with your setup and see if it feels better. Try the DM10, if it still doesn't feel perfect, exchange for a TD9, decide you like the DM10 better exchange it back. I'm not one for abusing return policies, but the way theirs is written practically begs you to do something like this.
If you do go that route I would the whole grace period to tweak everything I could. I've had my DM10 studio for about 3 weeks now and am still changing settings and how the drums are arranged. I've already done the mesh head conversion, jumped on the Superior Drummer 2 deal, moved the snare to a stand, and have configured the rack in every way humanly possible. Next step is get a pintech hi hat that can be used with a stand and possibly moving the whole kit to stands. I can already see an A to E conversion in the not to distant future...
But basically, I've been struck with drum ADD in order to get the "perfect" setup and feel for me(basically duplicating my acoustic set). Is the kit playable as it is right now? Very much so, and it feels pretty good the way it is. Hell, it was playable right out of the box, but it's still not perfect... Point is, it will take time and money to get that perfect set up just the way you want it. Just make sure that you have a stopping point and not to lose sight of your goal, which in your case is recording
