I concur with that and I think ATC is aware of the turbulence experienced on really windy days (due to mountain wave activity?) A mate was once issued with a block clearance from ML Radar when flying through there due to the turbulence, as he was going up and down like a yoyo. And that's the area where that GAM Aerocommander came down last year in turbulent conditions.
