While I have not flown this year's Frenzy, I have sessioned with a few friends who were flying them last week. I was on this year's Ozone Summit and they were on the 2014 Ozone Frenzy. From my perspective, the Frenzy flew great. In the lightest of winds, 8 - 10 mph, one of the the riders was flying a new Ultralite Frenzy. NO problem. I still fly my three year old 13m Ultralite in those conditions. I love how the Ultralite flies in very light air.
While I have not yet flown this year's Frenzy, I do know this: The design improvements that Ozone makes to their kites is very incremental. Their wings are so refined and they have such a history of performance that big changes are not necessary. Small improvements in design seem to be the rule.
However, one area where a big change did occur throughout Ozone's line is the Megatron chicken loop. This was fully redesigned. The flag-out safety now goes through the newly redesigned Megatron chicken loop. The leash now clips below this release. The new Megatron is now a push away design with an extraordinarily compact and positive feeling release mechanism. Reloading a released Megatron is easy even with heavy gloves. The Megatron also incorporates a swiveling barrel which allows the ride to easily untwist the flag-out safety line while riding. So if you are looping your kite one direction only, line twists are easily eliminated on-the-fly.
I hope this information helps. Where are you located? Is there any chance that you could get an on-snow demo to fly?
