Look at your prayer wheel. At FL350, Vmo of 340 (?) is equal to M0.97! A Vmo overspeed at these altitudes isn't going to happen.

I don't fly the 737, but as you are in Mach at 370 and you will end up cruising in Mach when level at 350, descend in Mach and VS -1000fpm, or B2N2s FMS mode.

Boeing may say that, but won't it be a writeup and engineering inspection? It is in my "Boeing". OK if you're going to end up in a maintenance base... Oh and the FDAP...
