I have found that with a 35mm camera on a bright day and ISO 400 film a red filter plus polariser still give speeds that are handholdable. It is a dramatic effect and in the right scene well worthwhile doing. If you want to use a tripod then fine but if you don't normally carry one then check the shutter speeds obtainable with both filters. I'd be surprised if you cannot handhold at said shutter speeds.

Depending on your latitude, lens and desired aperture and of course light conditions, you might manage handholding at ISO100 withn the combo of red plus polariser.
