For life surge I think it depends how long is left on BFB cooldown, if there is like <9s on B4B you should hold life surge so that the crit benefits from the +30% of B4B.

Saving life surge for every B4B is not alot worse than using it on cooldown. Ignoring DE and HT buffs, over a 320 second period using life surge on FT assuming FT is always ready as soon as it comes off colldown, then using LS on cooldown vs with BFB is like 3217.5 potency vs 3267. So not alot of difference. However life surge will not always be used as soon as it is up like BFB can because you will need to wait for FT. So basically need to just use best judgement on when to use it.
