We would love to have you!  We plan to add dash support tomorrow.  And our scrypt pool is always a good bet for your L3's!  SHA256 is a bit slow with the low (currently) no power on our pool, we are working to find some new high paying coins to add to draw support on those.  You are more then welcome to throw those on here as well, but currently it may be a better bet on another pool for those S9's.  Always looking for coins suggestions as well!
