The fees can get pretty high between a large Phoenix payment, the boltz fee and the main chain fee that way, but I have done that several times.
Breez also does it right from the app through boltz a little cheaper but sometimes I have wonky experiences with Breez and failed payments so I haven't specifically tried that way.
I get caught between not wanting extra steps but also intrigued by trying something new just to compare to how I've done it in the past. 🤷
Have no idea what sideswap peg out fees are compared to using straight LN boltz to on chain.
It also might make me a shitcoiners. 🤔
