AVID Flyer With 582 and Floats

[lv2plyguitar 172]

I have the original AVID gel coat floats that are under 200 lbs.  I am wondering with the 582 what kind of performance I can expect.  Can you haul two people with floats?  What is the general take off distance with no head wind.  What can I expect the cruise speed to be.  The dry weight of my plane is 568.  It has the 29' 10" STOL wing. 

 

Thanks
