Need help with stat weights

Okay so I’m sitting at 38% crit on my BM Hunter and I have two open gem slots, I’m curious should I be putting in versatility gems in those two slots now? At what point do I stop going for crit and pushing another stat?

I by no means am an expert of BM stat weights. Believe it is around 30% crit. I maintain crit and haste at 30% (both slightly over atm). Hardest part is finding gear that lets you grab versatility or mastery. Currently I am socketing Vers.

Raidbots.com will sim your toon and tell you your stay weights.
