I honestly don't see the point of using 1.0.1. It's rather easy to circumvent the crazy fee in 0.6.0 and base hash + fee hash in 0.6.0 is above the base hash on 1.0.1 (with or without fee).
Plus optiminer now has implemented an ssl connection for his fee, connecting to his own (solo ?) mine (proxy.optiminer.pl:4041) which checks the certificate so impossible to hijack the connection now.
Trying to strace/dbg the process is crashing it so hard to say now how much fee he's pumping out of our rigs.

Long story short : I'll be sticking to 0.6.0 until there's another linux miner with a decent fee or until optiminer get his act together and adjust his with more transparency.

PS : my rx470 is hashing at (not counting fee hash)
~170sols/s with 1.0.1
~160sols/s with 0.6.0
