Newer vinyl line will probably have even more of a plastic taste. If you're sensitive to that flavor like I am, you might consider switching to a barrier tubing like accuflex bev-seal ultra. It has slightly less resistance than vinyl lines, so you'll need to make the lines a little longer to compensate.
