Bed Problems - Carbon Fibre & Dial Gauges

My MDF bed seem to warp at the slightest opportunity, I have been looking at replacing it with aluminium, but have just ordered a sheet of Carbon Fibre Board (3mm thick) as this would be much lighter, any other recommendations?

Also I have been looking at making a mounting for a dial gauge on the print head that could be used to manually level the bed, but removed before printing.

Notice that a dial gauge will put downward pressure on the bed (move the bed) and a that the relative weight of the of the dial should be the same as the hot it substitute as to put the same twist to the x-axis or your measurement will be wrong as seen from a free hanging hot end



Edit: If you look closely at the picture you can see I moved the aluminium heat spreader down as a support for the original MDF bed
