There's no need to get defensive with @Dr JIM. He just has his views that certainly make sense. Again, this thread was only to start compiling data so we could have something to reference. It may stand that the 8-10x rule be true, however, it hasn't been this way in my experience. Maybe it's because of my age and weight? But we need to start comparing these things somewhere for info only, not to start a pissing match.
