Here is another, more simplistic, way to view it:
If, for whatever reason, you found yourself in IMC would a) or b) give you the best chance of survival:
a) having no experience flying on instruments
b) having some experience, through instruction as suggested by the OP, but not being current
If it was you would you rather have a), or b)?
The debate here seems, for some, to have lost all sense of logic.
