CE Hot Spring

So.. I have six, limit break or not?
What do you think guys?
I know we can obtain it easily through Damage Point in rerun...
But if you were me, will you use it on each servant of your party or limit break it and use it on just one servant? <- I talking about the event rerun... too early to ask this, i know it

Edit: one more question.. CE for Saberlot, Another Ending lv20 or Limit Break Hot Spring???
