I need some XC ski advice. I have done a little research and talked to AI a bit but I need real human feedback.

I am currently rocking a beat up marketplace find that beats walking but from using them every other day I can tell they are not optimal.

I am looking for a pair of classic skis for staying on the machined track. I am 200cm and 110kg. The weather fluctuates between -40 and -6 celcius where I live so I am thinking I should do fish scales or skins? My boots are NNN.
