Chance, if it were me, you have a sick board like the poster above me said. Why not get a board to compliment your SL? Maybe getting a Westmark / Blacklist, something with a different profile, true twin, and slightly softer, would compliment your SL well.
Just a thought. Like others have said, your SL still has plenty of life, and getting the second board if different enough, could provide you with another option.
