My company sops explicitly forbid use of V/S at all above a certain flight level as the Aircraft will disregard speed to get its desired ROC, possibly leading to alpha prot etc.....
Shouldn't get to Alpha Prot. If a too high V/S is selected, the speed reduces, but when it gets to VLS the Autopilot ignores the V/S command and will maintain VLS. The FMA will still show the demanded V/S.
oops, wrong term, doh! right sentiment. thanks!

Basic point I was trying to make was that it will neglect the speed for the sake of ROC.
cheers.
