when to add cherries to my sour?

[toejam]

Hey all, I have a mash sour that has been sitting with Brett for a year now and is now down to about 1.005 and I think it is ready to pitch some cherries into. My question is should I rack the beer away from the pellicle and into a new carboy before pitching the cherries or just pitch the cherries on top of the pellicle and let it go.
thanks for your help
