Oh no, my SQ-14 with windscreen addition is awesome for my 5 gallon batches. I'm assuming that I'll need a bigger burner when I move to bigger batches and using something like a keggle. When I get there, I'll probably get the Blichmann for the kettle and use my SQ-14 for HLT.
Till then... The SQ-14 is kickin' some arse!
