Help me get my first board

Hi everyone,

I'v been riding for about 8 seasons now (so about 50 days on the snow) and am thinking of buying my first snowboard. I already have boots (Photon dual boa which I got second hand this year) and im kind of confused by the shear amount of boards avaliable. So, pretty much, I need some advice in which direction i should head given the specs im interested in:

I am 185 cm and 78 kg, ride a 47 boot (so 32 cm). From renting bords I figured I need a 168w or 170w. I want a board that i can ride on groomers and powder. Where i live we dont have parks so i mostly hit side hits, so i would also like switch riding capabilities. The budget is 300 euros

Tbh i wasn't even thinking of buying a board yet, however, my friend borrowed me his Nidecker Megalight this season and I was amazed in the DIFFERENCE compared to the elan and nitro boards I rented.

I'm greatful for any advice!!!
