Hey thanks Elle
The topsy tail is very comfortable for me, but I did end up taking out the last "topsy" because it was getting caught on my collar and bugging me.
It takes a while to master the thing, and if you start with a tight pony than it does make it painfully tight after the twist. I can wear it with a single pony or divided, it's actually more comfortable for me than a regular ponytail. I think the key to doing it with all your hair at once is to wear it at the nape of your neck where it does not put pressure on the back of your head.
I used to wear my hair like this as a young girl and was suprised at how elegant it looks as a grown up!
