General consensus seems to be that the Baader film is the best thing
available. It has the advantage that, if you're at all handy, you can buy
just the film and make a holder, thereby getting a really good filter at a
really cheap price.

Watch those DSCs - I've seen a couple of guys who would go out to the
observing site, set up the scope, fight with the DSCs for several hours and
then it's time to pack up. Do the fighting at home in comfort, in the
warmth, in the light, in a clean environment. When you are sure they are
working and you can set them up faultlessly every time then take them
observing - don't waste your valuable clear sky time playing with hardware.
