Comparison between standard tig torch & gas lens ????

[rustycase]

I'm lost !

I have seen the one depiction of tinted flow from a gas lens compared to a standard nozzle, but I would like the chance to review some manufacturer's efficiency chart, with lines/graphs/arrows that show just how much more effective the gas lenses may be.

Does anyone know where this info is presented?

Also, my Super 200P came with a W26 torch, and our kid has let me use his Radnor W17... I like the W26 btr because it's more easily maneuvered because it has two hoses which are more flexible than the supposedly superior single hose, which is actually rather stiff and tougher to manage...

I'm considering a W20 to use with city water or a W9 just for ease of use, and I'm not doing anything hi-amperage yet...

Is there some place (specifically) where the actual sizes of the torches are compared in a graphic method that is ez to see ???

Unfortunately, LWS has no in depth display, and I can't see a welding expo being conducted anywhere near which I could attend to see ALL the goodies available...

Any help would be appreciated.
Tnx
