I guess the only way to deal with this would be to either try and predict the cutoff where BLAS yields better performance on most machines (probably futile -- different machines, different BLAS, nevermind the confounding factor of the outer dimensions, etc.), or make the behaviour user-specifiable.
I would favor making the behaviour user-specifiable with a default 'auto' mode that applies a reasonnable cut-off in terms of dimensionality to switch behaviors. G
