When your talking Snowboarding... to me There are three different types of boards (wait for it im gonna get flamed for this).
Park/Pipe boards = well Pipe/Park maybe a little bit of the mountain too
Freestyle = All-mountain : Pretty much the same at least I've found it that way. Both my Anthem and Timeless say they're all-mountain and they're great for popping off tricks, while doing some good carving, and they're both okay in the Back country. My ride prophet I bought from this dude that said it was All-Mountain and its more of a Freestyle oriented with some Pipe/Park traits thrown in there.
Freeride = I actually have no clue what this actually means. I think that it means someone who just likes to Speed down the hills/Carve and loves the Pow and Backcountry. Please correct me if i'm wrong.
it looks like your board is meant for just doing a little bit of everything on the mountain, just more oriented for quick tricks and shit. I've never ridden a palmer but I wouldn't worry too much about it. You already bought it, try it out before you go and waste more money, I've ridden multiple seasons on a bad selection mainly cause I was poor but also because I didn't want to have to waste the money on a mistake.
Hope this all makes sense
Enjoy the silence and peace!!
