I think if you want SPS, you can't go wrong with a power module or even a dimmable sun power. 8 bulbs will be great for your set up. I run leds on my LPS and zoas and will only even run leds for LPS. I run T-5s for SPS and the only thing I would replace my T-5s with is MH, even then I would supplement with T-5s. I like the warm glow and how well the T-5s cover everything uniformly.
