What shocks should I get? Fox or Elka?

So I’m looking for new shocks for my 2016 850SP.. does anyone have experience with https://www.amazon.com/POLARIS-SUSPE…/dp/B00MQ7XY94 which appear like they are fox made shocks for the Polaris? Polaris part number 2879892.. On the Fox website they recommended the podium 1.5 RC2 shocks, which are $600 more than those other fox ones.. On the other hand I could buy a set of Elka stage 3s for about the same price as either of these..? Am I completely crazy for wanting to spend $1500+ on shocks for my atv? Give me your input please!
