Personally I found better results using Flourish however my results with CSM+B were inferior to the results I see others acchieve with it.

I tried mixing and matching them too, 50:50 for some time to avoid wasting the CSM mixture I had made up. Worked better for me than CSM on it's own, then I started using Flourish Iron. Have to admit though that even Flourish on it's own is just fine, it may be lower than CSM in iron but that doesn't mean it doesn't contain enough of it...

My 55 gal (4wpg) gets 10ml Flourish, 10ml Flourish FE, 5ml Vita once a week or at times every other week when I delay water changes for a week.

That's going to be hard to say, I'd suggest starting with Flourish on it's own and when the tank is running decent, try to add FE and see if you get better results. I dose everything at once BTW.
