I forward on average a little over 1 Btc / day profitably (different node than this SN ID haha) . Mix of manual and automated

I think you're spot on with that liquidity flow you described, and many have posted some great router docs. Ill share a bit of my thoughts

As a pleb, I think many would be better off identifying and focusing on a SPECIFIC flow rather than trying to act as a generalized router. Plebs with 1 BTC are never going to compete against the big 40BTC+ router hubs in terms of real routes - its a liquidity game, and they have more than you

What I mean very specifically by this is, focus on facilitating a specific flow. Breez -> WOS is one example that I know is quite profitable ;) . I think many would do much better for themselves and expend less effort to focus on providing a highly reliable route for such flows, though there can be challenge in identifying such
