From benchmarks to real world experience I'm wondering if a single TI would be better for my build and it would be fairly easy to make the swap. Just want to make sure its the right move to make. What are your thoughts on this?

Consider the driver support leading into the future, After Nvidia's next launch (or refresh) the drivers pertaining to your Pascal SLI setup may not be as consistent as they are now. DX12 does not handle SLI or CF very well at the moment, so consider that. As always, a single fast gpu will always be the better bet, compared to two slightly slower cards.

Also consider the games and resolutions you plan on playing them at.

I've always gone 1 card then 2 of them. A new bigger better single card, then 2 of them etc. I've had no problems with SLI. But what I do now doesn't do Crossfire too well.
I use a 750W PSU. So my one or two cards always fit within it's capability. See www.realhardtechx.com/index_archivos/Page362.htm You need an 850W PSU for gtx1080ti in SLI. A 750W PSU will do gtx1080 in SLI.
Also when I go from 2 to one cards, I check that the new card will work better than the last 2 cards in SLI or Crossfire. eg before 2 R9 Nanos, I had one R9 Nano. Before 1 R9 Nano, I had 2 x gtx670's in SLI. The jump has to be worth it.

If your applications can't use SLI then change to a single gtx1080Ti. When you sell the 1080's you should in fact end up with more cash left over after buying the 1080ti. If SLI works fine then leave it as is. 1080 sli will perform better than a single 1080ti. But either will be fine with your monitor.
