Best practice is 2-3 channels minimum to reduce routing failures and improve redundancy if one of the channels is offline for any period of time.
Sizing: consider the biggest payment you’d expect to make and/or receive and double that. That would likely be a decent size for each individual channel.
🙇🏻♂️ Guessing that goes for both receiving and spending channels. LSPs seem geared towards increasing my receiving capacity while the...other kind seems to afford me spending liquidity.
Yes, LSP channels will be all inbound (receiving) when they are first opened. You can somply open an outbound channel of your own to a well-connected node for the spending side of things.
