I`d say Backflip is a good mag also for young people. It has pictures, interviews, profiles on junior gymnasts, posters, prizes to be won, ballet hints and tips as well as training tips.
Carina - you were correctly informed. Last year Backflip still had 6 issues out per year. They just reduced to 2 issues now. I donīt really know why. However, these two issues will have 46 or 48 pages which makes up a little.
Paying via Paypal is no problem at all. I use it as well to pay for my subscription.
