I'll have to look into wubble bubble. It sounds cool. I'll not tried too many balloon brands yet. The one I like least is a grocery store brand I tried, which only went to nine inches.
Way to Celebrate (Walmart brand) is pretty decent for the price, although it takes a few weeks for those balloons to soften. The ones that are about three months old are super soft, now - and heavenly to the touch.
I just got Unique last week Wednesday, and it seems that they'll soften much faster. They're about as soft as my five week old Way to Celebrate balloons.
How long does it take for Cattex to soften? And do they usually have pronounced drip points? What about Rifco.
