Light/Reduced Weight BARS: Which are solid, which are laminated?

[EchoShindaiwaMakitaDolmar]

Which light/reduced weight bars are made from a solid piece of steel, versus two or three layers laminated together?

I'm looking at Stihl, Husky, Oregon, Tsumura, and Sugihara, and would like to avoid the laminated ones.

Thanks

If it has a replaceable nose chances are it is solid. There are, probably were some GB bars that were solid but the nose was not replaceable. On the hard nose Oregon has both a solid and laminated version.

Are all the newer production Stihl ES Light bars honeycomb inside the milled out area?
