in the exact same boat as you OP.
been snowboarding forever and decided to pick up skiing a couple weeks back. got some el rey's for cheap off a member here and some old SPK's with Squire bindings (I know, I know) and been out twice so far, absolutely love it.
I don't even really see it as switching as much as just adding another option. Whatever I'm feeling on the day, I grab... or you could bring both to the mountain and switch halfway through the day. I find it's great because I'm up at the mountain (if you can call what Ontario has mountains...) by myself a lot because my buds are lazy and didn't get passes, so it's good to switch it up and keep things interesting
But definitely go for it man, it's a good time. Feels great to be learning new things every run and getting more and more comfortable out there
