I don't think you will gain much from your current binos going to Swaro's, slightly better resolution, better edge to edge but if you can't judge a buck at those distances with yours the Swaros won't make it so you can judge one at the same distance.  I'm not saying the Swaro are not better just that they both serve the same purpose, just one will do slightly better than the other.  
I also agree with everyone above about the spotter, IMO the quality of a spotter makes a bigger difference than that of a bino since there is so much more magnification.  A small higher-end spotter will do a better job than a cheap large spotter.  You will find more and it will be clearer with a Vortex Razor 65mm than a Vortex Viper 80mm.  
I currently have 10's, 15's and a high-end spotter, for finding deer nothing replaces the spotter, I will be packing all 3 on my deer hunt this fall, a good pair of 15's are awesome for finding deer that may just be brushed up or in the shade.  Essentially once the 10's are not effective the 15's stay effective for a while longer, I have picked up sheds with the 15's that I have overlooked for a couple of years with 10s and a spotter due to the combo of decent magnification and larger field of view.  Unless you have a really good system with a spotter it is easy to overlook game when scanning, you really need to overlap when glassing to be effective.
