Well after trying this out on 50 odd photos it appears that it produces very acceptable photographs, with a lot of punch and clearer (grmiy, horrible light, haze etc improve amazingly). After experimenting I can achieve pretty much identical results by, upping the clarity to 65+, brightening a tad, applying a reasonable S in tone curves, slightly more contrast than medium, and upping the sharpness to 70+ with a mask so it is just for the edges.
Would I buy it, no not now but I have learnt a lot more about LR in the process. If it was say $50 instead of $200, yes, think I would.
