Body English then use the kite.
Load n' pop; lift your front knee, drop your front shoulder, look back over your rear shoulder*.
You only have to get half way around, as the pull from the kite will drag you around the rest of the way...
If you try to rotate all the way around with your body using momentum, you'll get spanked if you get lifted at all as you'll over-rotate uncontrollably.
* bend yourself without leaning - imagine a kick boxer using a shin/forearm block, balancing on one leg.
Feels wrong to me too :) I much prefer to do a sent front roll, using the kite to lift me and only doing the (partial) rotation up to the zenith, then redirecting the kite and using it to nail the landing... doubles and triples are much easier as front rolls though.
This is all assuming that what you mean by "front roll" is what I mean by front roll
