Galahad is correct here. A Baal predator should never have heavy flamer sponsons. Note that they have the same str and ap of heavy bolters but only work when the enemy is in charge range of your tank.
A pintle mounted storm bolter (taken in addition to the aforementioned sponsons) is quite a good idea on a baal. It gives the thing 12 shots, which is a lot of shots. For the amount it costs I'd say it's almost a no-brainer to stick pintle storm bolters on all BA and DA tanks actually.
