my vinten pro is overkill for this camera, any suggestions on a good one with fluid head

I'm using a Sachtler FSB-6 with Flowtech75 legs. Super smooth and easy to balance. It's a very nice combination that will meet my needs for any of my small cameras for years and years.

#1 for little FSB Sachtlers...I actually have the Cine-DSLR head, which is the same size as the FSB4/6/8 but has extra counterbalance stops for more precision with smaller cameras. It's all about counterbalance variability...unless you just want to lock it down.
