Weapon sync swingtimer for enhancement

Anyone use a weapon sync swing timer weakauras like this https://wago.io/joURtkngg ? I tried to use some from wotlk classic but they are not working.

Don't use any swingtimer addon but it's quite interesting to read that MS stacks prevent a swing timer reset even when you have just one stack of MS.
So when you use a slow two hand it should be technically possible to hard cast LB after each weapon swing without losing any attack speed.
