Markbass little markII 210 combo

I play a hartke 3500 with a peavey TX410 and a hartke transporter 410. I'm thinking about selling the hartke head and cab to buy a markbass little markII 210 combo...

I don't really like the sound of the hartke: to clean and hifi. I want something with more warmth and growl. I would also like a bit more power (the markbass has 500 watt vs. the 350 watt hartke) since I have problems hearing myself at rehearsel. I was thinking to put the wedge-combo on top of the peavey cab to get te sound right to my ears: I think I will hear myself better this way...

Any suggestions on this topic? Any experience with this markbass combo?

Thanks
