When setting up for a longer range western or tundra hunt, I always reach for my two blades. They are solids - not vented, but I have never had a properly tuned setup let me down.
I've taken a ton of caribou and speed goats at 100+ yards with zero issues, and that's even with substantial wind.
One key that I've found (as others have alluded to here) are to shoot the heaviest/stiffest setup you can tune well from your bow. I've never shot anything less than a 125 broadhead, and nothing less than a 600 grain arrow. I don't get super techy with the whole FOC thing - just find a setup that is on the heavier side of the spectrum and that tunes perfectly from your bow. You should be able to bare shaft tune out to 50-60 yards without issue. If this tuning is spot on, you should be able to close your eyes and pick a perfectly balanced broadhead and it should shoot well. I just have had the best luck with 2 blades as most are heated to an insert so I could spin test them until they met my personal opinion of balanced.
