So, your opener should be: consume 3-4 stacks, then rop+comb, pyro blast pyro (blast pyro), flame on, blast pyro blast pyro.
You should get all that through during your ROP + comb. and by the time your 10th stack is consumed and your trinket fires, your ROP should still be up.
For later activations, you look at your remaining time for the boss fight. If you cannot get two out anymore, delay it for next comb. If you can get more than 1 out still, use it on cd. Important though, to having ROP active when you consume the last stack!
