Yes I did Google the topic of blade profile on LA-BU smoothers and there is a LOT of info on the matter, maybe too much. All seem to agree that iron profile needs to have much more camber than a standard BD bench plane.

My Veritas LA-BU smoother came with a 38 degree iron, with no camber.

One site says it is VERY important and much easier to start with the 25 degree blade and grind in the camber with higher angles on it, as it is very difficult to grind the needed camber on the 38 degree blade. So, should I send my 38 back and get a couple of 25's?

I would really like to know what any of you do, who are really familiar with LA-BU planes, regarding the camber on them.
Thanks.
