Don't take this the wrong way (as I really like the idea of this pool), but what are the advantages of mining here vs. real solo mining, assuming I already have a full node up and running?
With gbt

Bitcoind does not support stratum and running full node well conected costs money ram cpu and bandwith...Chances to get orphan/stale block with home node are very very big. So unless you are
NOT 100 sure what you are doing just spent 0.5% for fee and this will get back to you milion times if your are lucky to find a block
It worts trust me
