I have never heard a "backroll" being called a "backloop" before. Is this a regional thing?
Riders roll, kites loop.
I've only heard british call it a back loop - others seem to go with back roll.
so here's an international dictionary
backloop: british guy doing a backroll
back kite loop: back roll with a kite loop (see also back roll kite loop)
back loop loop: british guy doing a backroll with a kite loop
