I ve been using the Renegade for few years now and loving it.
This is a great all around kite, has some great pop, insane water relaunch and awesome toy for the waves.
It actually comes with an extra set on 15m lines to use in the waves and make it super fun and fast turning, nice detail from EPIC.
If you are looking for a kite that :" I want this new kite to give e a bit more pep, be a little faster, and provide better lift ", I d suggest you to look at the Screamer 10Ltd that has the pop/lift of the Screamer line but a bit more grunty with more rounded wingtips to make it a great wave riding kite.
I haven t flown the RRD neither the Fone so won t make any comment on those kites.
