Lee, in all honesty from the tenor of your posts, the T4/T3 will be a perfect fit for you.

You will find the FSX action quite nice to play

I truly would not hold out much hope on the PA3 being that much different on the orchestral side of things. Perhaps only with a select few individual voices, and in my view DNC has quite a ways to go to match the S.A. on the Yamaha.

The PA3, so far on what has been gleaned, is possibly more like a PA2+, rather than a full on total reconstruction of the OS and voice banks. Physically very, very nice (apart from the ugly speaker add-on) but operationally much the same.

So, yeah, go for the Yammie m8, especially if you liked Telmos efforts (excellent btw). You will not get a similar result on the Korg.
