Definitely a Mantis.
Check the tail strap on the back side of the spine for more identifying information.
Mine is a UL. Black Diamond 3pt lower spreaders, P200 spine, P100 lower leading edge. Sorry, don't want to de-spar the kite to see what the upper leading edge is, but that should be enough to figure out if you have a UL or standard.
i found some specs for the Mantis on the web that match my quick measurements of the kite, also read several positive reviews...unless Ken made other models with the same measurementts as the mantis, then i guess a mantis it is.
hopefully the Level One will be as easy
