With the white pens lots will work but it depends (well at least I think it does!) on how wet the pen goes on. You just have to play about with them. I agree Eddings are good but they are expensive and I found that they dry out pretty quickly. I have got a couple of huge ones that work just fine.
I have bought some Painty Pens from Up Up (I think) but these get very wet with a little use and the nib from one fell out whilst I was working and has ruined one of my tops!!! Best find yourself a selection and just try them out on untwisted inflated balloons and then it's not too heartbreaking when they pop

and perhaps outside unless you want a speckled look in your front room LOL
