--xintensity 7 works best for me (no stales)
(I assume Nicehash does not pay for stales.)
Yes there are optimal defaults for each pool. But --xintensity 7 is low. Other pools run fine with --xintensity 64 and ~100MHASH.
I just like simplicity of Nicehash even if it means less profit.
And TBM gives 3-5MHs more (with this setup) than other miners, great job :-)
