What cart have you got on your SAT Matthew? My SAT came with an armboard for the AF1 from Marc so I'll be using that. My Ti board is made for an Elite.
I am using Koetsu Blue Lace with diamond cantilever at the moment.
If you have the ti board for the elite already, I supect you may find the SAT with aluminum board a little dark in comparison.
As to the question why not get a stainless upper platter instead of ti plus the tungsten, extrapolating from my previous experience with Micro SX8000-2, i don't think the two would be even close. Ti platter is much more lively and warmer. Really one will have to hear it. Not sure if you have tried it, but actually just replacing the headshell screws with titanium ones will give you a taste of it. The ti platter just gives a bigger effect. BTW the ti screws from Dietrich of Acoustical Systems for some reasons sounds much better than other generic ti headshell screws i tried. Not sure if it is the alloy or something else... Also those with DLC coating can be very good.
