pro hurricane hybrid moves a lot

[ysi]

I just got my 300G strung up with pro hurricane 18 gauge mains at 56lbs and PSGO 17 gauge crosses at 60lbs. The first time I hit with it, the strings moved around more than I expected. My stringer says that certain cross strings will grab the mains better than the others, it this true? Which syn guts grab better?

I previously used super smash 16 and gosen micro 16 and that combo didn't move for weeks. Might the difference in gauge of string affect string movement?

I used to use hurricane 18 mains with syngut crosses and didnt have any problems with excessive string movements until it went dead. I dont hit that flat either.

gamma syngut w/o duraflex as a cross with pro hurricane wont even move using my hand, and it didnt even move that much after hitting
