Dual-Spectrum Analog vs. MH/HPS Digital

Okay, so here is how it is:

I have an array of 540w CFL bulbs which produce ~22,000 lumens.

I want to buy a better bulb with a ballast for two reasons:

1.) My plants aren't growing very fast under the CFLs.

2.) I need something for flowering, which the CFLs won't do.

So, I have to get HPS, which means getting a ballast.

Question is - which ballast? Digital is better but I can't find it near me so that's another week of subpar crops while it arrives.

But I also need Metal Halide if it's going to replace the CFLs for vegetation, right?

What about Dual-Spectrum bulbs? They work on analog ballasts and I can get one right away.

But will DS be as good as MH for vegetation?

Really appreciate the input!
