Which support material to use?

I am looking at a two extruder head soon. I have to decide on a one or two nozzle one. Regardless, this is a home hobby thing and I am unlikely to use a nasty chemical dissolver for my typically PLA projects. What would be a good material to use if I just wanted something super brittle that snaps off?

Thanks,

There are 3 options (beside using 1 head, and the same material as support)
-Hips, but there you need chemicals to remove it.
-Pva, only tapwater to remove this material.
-Polymaker's Polysupport. Easy to remove, but functionaly the same as using the same material, but with almost no traces.
Ps, dual extrusion (what you need for there support options) is not easy, and requires quite a lot of practice.

Quite a lot of practice?
I think that describes learning PLA and ABS printing perfectly well. So what else is new!
Part of what makes this fun is the constant learning curve. Two months ago I got a Kossel delta printer kit. Now I have dialed it in enough that many prints are routine, but everything new takes tuning and practice to get right.
After I "perfect" my ABS process the next logical step is a dual head of some kind. Then try a Cartesian printer to see what makes them different, while at the same time learning how to use CAD packages.

I am not going to be bored for a while.

Is the PVA filament of any value as support?

I have not seen a filament that adheres enough on PVA so that it can be printed with this support. Maybe someone knows one and can share with us.
