just has to be the right pitch to match your current drivers. as far a track goes. unless you are putting in new drivers as well.
but track price depends on what your budget is. new or used? wouldn't hurt as mentioned to put a different skid in to your track length. I have put in rmk skids in before to get away from extensions on my buddy's sleds when he went 151 on 1 sled and 156 on the other. plus you can usually pick up a good used skid pretty cheap.
