Freestyle gliders with low weight

Hi,

I want to begin acro and I am currently checking freestyle gliders.

I've tried so far the 22 Octane (18,40 m2 projected), RR rolling 22 (18.60 m2 projected) and some EN-B at the far top weight limit. I want to give a try at a Gradient Freestyle 2 before I make my choice.

I weight 75kg all equipped. I've liked the dynamics of both gliders but wouldn't go for something much hotter than that as a starting point.

The Freestyle 2 22 is 19.2m2 projected and will probably be less dynamic especially with my low weight, is that right ?

Will a Freestyle 2 in 20m2 (17m2 proj) be much hotter than the octane and rolling in 22 ? I can't afford a glider for thermals and another for freestyle right now. Is the 20m2 still a good option for let say 70% freestyle and 30% thermal (not talking about going XC of course :-) ?

I will try to test both but want first to have your opinion on that.

Cheers
