Tmation said it all, Stu. In general, you'll find shorter cans tend to give a bit more at peak rpm but at the expense of a little off the low end. It's a back pressure thing. As an aside, please check your PMs and get back to me via e-mail to arrange details of your 'Ivanising' appointment in September. Thanks.Mike
