Malibu kayak X13 or stealth 12

[45user]

So the parking lot sale came earlier than I thought and I wanted to pick up a shorter yak. I currently have trident 15 and like it a lot for its speed. And want to pick up a back up yak preferably shorter one for using it in the harbors and bay and occasional long distance. I'm 5' 8" and 185lb.
Between those 2 kayaks mentioned above, how's the performance in speed and trackability(?)? I had mini x and took it out once and I switched to trident because how slow it was.
I like the features in stealth 12 but is there a lot of trade off in speed compared to little longer X13?
Thank you for your help.
