Need help deciding on return pump

[FPSD]

Guys I have a 150 gallon tank with a roughly 50g + 40b sumps. Running a synergy ghost overflow with 1 1/2 drain and 2- 3/4 returns. I will run a manifold for future use on the return side also. Need to decide on a varios-6 or 8. I am leaning towards the 8 and figure I can turn it down as needed.

What do you think? Sound ok or way to big of a pump. Thanks.

Personally, with such water volume and manifold I would go with the vários-8. You spend a little more but you'll gain flow power, flexibility and save on other pumps for reactors... my 2c...
