26 years.? I'm not sure any single bull can live up to 26 years of hype and hope. 400" bull or bust.? Unlikely if you're competing against guides who spend 24/7 sitting on bulls until Moneybags shows up. Plus, they're rare. Not all bulls can even grow a rack that big, no matter how old.
You want to get out and pursue mature, rutting bulls.? Get a Multi Season tag somewhere else. You could chase bulls for the entire rut with a rifle then a muzzy if you want... Not to mention Archery or late season opportunities.
I've been on Boulder and the Book Cliffs during the rut in different years while hunting deer. The sights and sounds are incredible. I spent 12 deer points in 2016 on a Multi Season deer tag in the Book Cliffs. I knew the area but still took one scouting trip, spent four days Archery hunting with my kids by me, then 6 days during the muzzy just me and my dad. Finally took a nice 4 point in the rifle hunt. He's not even a 170" buck, but that wasn't what I needed to feel satisfied. I saw more country, more new and untouched places, more elk, more bears, more deer, and more jack rabbits than ever before in my life. The time and the company is what mattered to me. Not the inches on a tape.
Decide what you want out of that tag, then do what you need to. Don't trade years for inches, neither are ever guaranteed.
