In my experience, standard barrels in the rifles that I have floated, and that's quite a few, have always responded with better groups.
The VLS usually comes from the factory with the capability for excellent groups, but that's not to say that they cannot be improved.
I don't own one, but I like the concept that Remington provides. IMO, a barrel with natural harmonics, due to floating, is ahead of the game.
