New Tank, new Questions

[Nano]

So I`m in the slow painful process of emptying my wallet over the next 6 or so months on a new 120g tank.Edit-- Dimensions - 4x2x2

wont go into all the details, but it will by SPS heavy, so I need opinions on flow

I have heard a lot of different answers from vendors so I`m fairly confused at this point.

Rock work will be minimal to allow room for lots of sps, I`m thinking MAYBE 50-75lbs in the DT at most. the rest will be in the sump. (around 50lbs of good live rock from my current system..

I am looking at Vortechs, but not sure which route to choose as I dont have a clue! lol

also looking at Tunze 6105 depending on the number I have to get.

and then my last resort is HYDOR Magnums but I`d love to stay away from these if possible

so heres the question

If I go with vortechs, should I do MP40s or MP10s? and how many

If I go Tunze which should I choose and how many?

I also know this could depend on a return pump, so if anyone has any thoughts let me know. I "think" i have the rest figured out (skimmers, lights, etc..)


Thanks

maybe in the new year I'll get to start my build thread lol.
