I've made a huge investment of time in converting from T2 to Pa2X, and it's really paying off. So it would take something really special to do it again (the other way).
For me, I really love the 76 keys and song book, so they are tied together. Without a songbook in the T3 it won't even get a look-in with me. OK, maybe when I am blessed to have breakfast with Donny he can take me to try it out......
