What are you looking for, regarding a "good looping" kite ?
Some seem to focus on a kite that turns fast ?
And this is typically NOT a good looping kite, if you want to do awesome powered kiteloops
But good for beginners of course
And a pivot turning kite can also loop REALLY fast compared to even good C kites - so even easier to loop
But NO power in this loop - so why do it at all ?
As I assume the fun with kitelooping is the sheer power and horizontal speed you get while doing it untill it catches you somewhat (or not...)
So IMO it is important to point out what one think is a good looping kite ?
Very very individual.
Is it a tight looping one as the only demand ?
Is it a powerful one ? (which goes in the other direction than the first demand)
Is it a C style one, or an SLE style more pivot and easy ?
Some of the good C kite freestylers, prefer the kites turn with a medium radius in fact, as the kite would be too powerless if tight turning (and it does not look good either - it sucks compared)
But even slow 12-14m2 kites can loop relatively easy, all of them, that is for sure
Sorry - have not flown the Cabs so dont know about these...
