I'm considering getting one of these kites and don't really want to change my bar (2008 OR bar). Can anyone compare them? I'm looking for stability, gust handling and which jumps better.

...oh..and I'll be primarily riding these in waves off SE Floriduh

Your bar would probably work fine for all three kites but might need a little tweaking. The Envy has a one front line flag system where the Renegade has a mini fifth line and the Razor comes with your choice of either a newer version of your bar or a mini fifth set up. To get your safety to work to the kites original design you might have to tweak a few leader lengths for the Razor and Renegade. The Envy might require a little reworking, but I bet it would not be all that difficult and certainly cheaper than a new bar.

Stoked with the Razors so far. A stand out kite for sure and aces in the suits you mentioned.

Ask these guys, someone might be able to compare for you:

I have not tried the Razors or even seen one yet. Have ridden the Envy and Renegade.
The Envy is more of a park and ride kite. A super wake style kite but I thought it was a little slow on the steering for loops and such. It is though probably the best in stability.
The Renegade was the most nimble and fun out of the 2 to me. The 11m Renegade is faster than the Envy 9m. Jumping and hangtime are excellent. It"s also great at unhooked wave riding.

Overall I have been very impressed with the Renegade.

You just need to purchase a 2011 SLE Bar Upgrade Kit to use your 2008 SLE bar with the new 2011 Razor. I have just taken delivery of an 8m (with the mini 5th freestyle bar) Just waiting for the wind to show to get on the water with it!

Envy is a sick kite. love mine.
very stable in the waves. floats nice. super quick relaunch ....
Solidly built, with no issues on build quality. Boosts nice too.
suggest you give the Envy a demo for sure, cant go wrong with ocean rodeo either .. solid kites.

I'm looking into the Envy's. Any recommendations for two kites for Florida. I'm thinking either 12, 9 or 15, 12 or 15, 9.

I've also considering a 15 Envy and 12 Havoc (better low end)

Any thoughts?

I've been out a couple times here, both times on my 14 meter rise. Not sure if I will ever have days to use a 9.

If your 14M Rise is the kite for your winds, a Razor 12M might be your kite.
Razors will be faster turning, better relaunch in light wind, more low end grunt than Rise, still with good boost and float, and still Ocean Rodeo tough construction.
