at 1.1, you probably wont notice a thing performance wise. do a serch on the gear forum on "triple" and you should hit a load of info from Mr Blue.....
I had trips on my AR-11 and changed them because they reversed risers. BAD CALL. If you are loading high (1:1.5+) Trips make a difference. They let the canopy flatten out increasing the lift on flare and reduce steering line wear.
Skydiving is not a static excercise with discrete predictability...
