There is one thing I will try with this update. The current fee strategy of lnshortcut.ovh is basically 0 base fee and 1 ppm for most channels, and 0 ppm if some channels need more inbound balance. What I want to try is to increase fees on channels that are sinks, up to to a point they still route a lot (let's call it a feerate of N ppm), but in the mean time, have a fee rate on source channels of -(N-1) ppm. So in the end, my effective feerate is still 1 ppm, but I get more traffic in the direction that didn't route, so also more traffic in the other direction that receives a fee
