Having that trinket isn't enough to make you swap from one spec or another, weapon availability should be the deciding factor there.
If anything you should be using the Abberation with the Lucky Coin trinket for Sub spec, as you don't appear to have 670 weapons for either spec.
Really you should be using the Scales of Doom + Coin anyway, as the MS proc from Scales has a big impact on Sub play. If you don't have access to the Lucky Coin the WF Abberation is a fine alternative.
In general you should just play what you enjoy playing or can produce the most damage as.
