Functionally, the 2019 and 2018 LXT are very similar. Both use the same type of composite in the barrel, have an ultra lite end cap (they call this the X-Cap) and use a synthetic grip on a 7/8 handle. (See our
2018 Slugger LXT Review).
They have "upgraded" the connection piece from the Tru3 to the VCX. Both techs claim to let the barrel and the handle move independently. We felt no difference between the newer VCS and the Tru3. But, we do know the Tru3 had a few durability issues so it is possible the VCX is breaking from that a bit.
We were fans of the Tru3 tech, especially in the baseball space. No connection piece, even the famed 3-fusion/D-fusion from Demarini compared to the Tru3. If the VCS is a better long term play, in terms of durability, then the Tru3 then we have no doubt we'll love it.
In other words, we don't see much change from the 2018 to the 2019 model. If you can find the LXT in a 2018 version new in wrapper and a discount we would suggest that one over the 2019 version (for price reasons only). But, when inventory levels settle down, expect both the 2019 or 2018 to be a really good choice.
