Morph Trimmers

Hi Pal!
Thanx 4 the advice concerning morpheus
I finally bought the morph 19, that would be arround 4.27 to 4.33 kg/sm.
I was surprisied to notice the good thermalling capability of the glider
Already did Wing-overz, then Full-Stalls, dinamic FS, SAT, dinamic SAT, helico attempts :)), no coconut yet, but managed to learn Looping. It's so easy with this glider :P.
I have a couple of questions:

1. The Trimmers: I noticed that if I release the trimmers I get a better glide ratio and a highly improved thermalling efficency. Does it affect the stability of the canopy in turbulent conditions?
I didn't notice any stability loss, but I want to ask you, cause I've had a nasty accident with the cidan in march 2007 beacuse releasing trimmers in turbulent conditions while soaring.

2. I am going to Laco di Garda and Omenia for 3 weeks of training starting the 2 nd of August.
I am planning 2 practice : loop, coconut 2 helico, helico, and helico 2 SAT ( I can do those, but need more practice)
And I want 2 learn: AS SAT and TUMBLING.
Do you have any advice 4 me? Other tricks I should try to learn before? What is your opinion?
Thanx a lot, Colin from Romania

P.S. I'll be there at Acroaria, maybe we see each other arround there
