You should see a higher yield by using both lights. The better HPS have an enhanced blue spectrum also to compensate for lack of blue light. Using both lights gives you all the light the plant needs for flowering. It does not work for vegging just use the MH. This is supported by research, LED's have also shown us what colors are important for flowering.

Yes, use both. Even if you do have a dual spectrum bulb in the hps, that extra light from the 250w mh will for sure make a big difference compared to not using it.

I had a situation where my plants were on MH when I had to switch to a HPS bulb and the plants tripped out! They just acted like different plants, growing really wide, strange textured leaves... It seemed to set the plants back a little, and they were much happier under MH for veggin, however both is best.
