I believe you well know the answer to your own question. Neither you or I can say how much research MikeBCda might do to see what the differences between the 5.5 version and any later version. However, it a mute point why go back to 5.5 when he is using 6.5.737 that is working for him and incorporating all of the points I raised and then some.
I'll stick with my 6.5.737 as long as it stays functional, but I'm fairly sure its days are numbered.
