flow advice for wanting to go SPS dominant

Hey everyone. So as the title says I'm wondering about flow. Over the next month I will be upgrading and trying to find the best option for my situation. Would love some advice from veterans. I posted this question over in the equipment forum but have only had one response, so thought this question might be best suited here since SPS is what I want to achieve and I'd be asking the people who know these corals the best.
I have a 92 gallon corner. A pain to get flow in all the areas but love the tank anyway. Currently have 2 K3s and 2 tunze 6025s. Not much flow maybe 30x, that's fine for the few soft corals I have currently but plan on turning the tank to all sps over the next year so needing to upgrade flow.
I was thinking tunze, 2 6045s that do about 1150g an hour and 2 6065s rated around 1700g per hour. I'm concerned cause it's about 60x+ flow but contsant. Not sure how the fish or corals would enjoy that.
So was suggested to me to go with tunze 6105, controllable which brings up another option. Was thinking maybe 2 which are very powerful so would hate to create huge sand storms or rip flesh off corals so not sure about this. I do like the idea of only having 2 powerheads in the tank. Less clutter the better but not sure with the odd shape tank even if at max flow if I would still have dead spots etc. Or was possibly thinking 1 6105 controllable and 2 6045's. But one person warned me that 6105 might take flesh off some corals since the tank doesn't have huge distances, so some of the nearer corals to it may suffer.
Then also thinking maybe bite the bullet on a vortech mp40 or 2. I hear awesome reviews except for noise and have never heard these pumps in person so not sure what to make of the noise levels. And since my tank is in the living room right next to the couch, loud pumps no matter the performance will get vetoed by the wife and kids.
Also I've read some of the reliability issues, which really concerns me a lot. Sure customer service may be good, but if I pay 400-450 then I don't want to have to keep sending stuff in, no matter how good the customer service is. Plus my wife has authorized upgrades but she would be awfully upset if I dropped so much $$$ on something that wasn't 100% reliable. I've heard very few reliability issues with the tunzes though, so that's a + for them.
So anyone have any suggestions? As you guys can see I'm totally swimming around in ideas and having trouble committing to what may be best for the success of the corals since I currently don't have any SPS and just simply don't know. Are controllable pumps really worth the extra expense? Or would the 4 tunze non-controllables be successful for sps? If controllable is the way to go which option would be best? Performance wise and quietness? Thanks all for input.
 
Not a veteran but the tunze are nice because of the directional options.

I usually have about 9k + gph flow in the tank. If you have fine sand the mp40 will be not so good. If you have the medium sand your good. I think for randomness you should do a controller for sure. The mp40 is sleek and sexy. Tunze big and practical I have both and koralias. I have the 6125. I like it for breaking up the top.

I would think in a corner tank 1 mp40 and a mp20 or 3 mp20 would be nice. Or do 3 tunzes something that handles 1400 gph+ each one.
