So I've never owned a pair of snowshoes and just bought a pair of MSR revo ascents. I'm 6'1, 190ish without a pack. The guy at REI convinced me the a 25" was the way to go and suggested that I could get the tail extensions to take the shoe to 30" when needed. My first question is does anyone have any experience with the MSR tails? Do they work well/are they durable? My second question is would I just be better served with a 30" shoe? I'm going to be using them in the backcountry for camping and shed hunting, so groomed trails won't be the norm. My gut says the 30" is probably the way to go but I want to make sure im not ignoring potential benefits to the 25" w/tails setup.
