What are generally good settings for equishash on a 1080 ti for equishash? like Zcash,Zen,komodo etc.

My scenario.  I pay .15 cent in summer and .22 cents in winter.  So power efficiency would be nice but I'm also looking for good balance with max profit potential.  Looking to sell these coins 1-2 years from now

For my evga 1080 ti sc blacks I use these settings
  -65 TDP,
 +125 core clock,
 + 300 memory,
Getting 630-650 hash rates
and getting 60 degree temps.  It's been very stable, I have not had the time to dial it in

I think i might be leaving some room on the table, What dialed in settings would you suggest I use for my scenario?
