yo!
it sounds a bit strange to me that you use blancos indoors. aren't they too stiff? anyway, I would suggest sportiva's cobras. they are the most used in gyms, and for good reason. for my foot they are a bit too wide, but they are an excellent shoe.
otherwise I'd say solutions (they're good in and out) or 5X from fiveten.
obviously, all the top notch models will perform well on plastic, and I mean dragons, solutions and so on.
which kind of climbing terrain do you prefer? that makes a big difference.
hope this helps.
