In an attempt to give "equal billing", there are other brands such as Swan that do the trick too!
Suppose powder paper - like pad-savers - everyone has an opinion on. Not exactly talc from what i've seen of them, more like French chalk, but suppose like for gymnasts, would be useful for keeping your finger's dry and not slipping off the keys in exams if not used on the pads!!!
Again, depends how people use them - if they're gonna rip them from under the pads then you may as well be using sandpaper. It's been said before, but close the pad on the ungummed part and open it again before removing. The 'gummed papers' only have a small strip of glue along the edge, not the whole paper otherwise it'd be a bit of a messy roll-up - not being a smoker...having a father who used to use them many years ago (still has an
original Rizla Roller from over 30 years ago!) Agree that the colours simply apply to different thicknesses (how about Rizla White or Silver for lightweight?)
