Pro tip after 10+ years of riding Unions - on a brand new set, strip them down and loctite the bolts.
Once you do that they should pretty much never let you down, but the factory loctite they use is fairly rubbish, in the early days I lost a bolt or two on the hill on new pairs.
I don't buy snowboard gear with anything like the voracity I used to, my mountain stick is a 14/15 Capita Ultrafear which pretty much does it all to a reasonable degree...and that's got a pair of Union Forces on it which must be coming up 8 years old now.
Riding rails indoors tanks your gear a lot faster, when I was riding indoor snow every week I would get through a couple of boards a year no bother...
I'm actually a park shaper at my local indoor slope, but it's been closed since pretty much this time last year due to Covid. Haven't strapped in since I had a concussion Jan last year, this has been the longest i've not ridden in about 15 years.
Get friendly with the distros, always a good way to get discounted gear that's kicking around the warehouse. I've had more than a few cheap boards over the years from talking to the right people.
Flow bindings are dogshit... stick with Union, Rome or Burton.
