I'm planning for an Alberta Moose hunt next year. My bow of choice looks to be my Rose Oak B Riser and 60lb Bear limbs.

2 questions, Am I using enough bow and what arrow would you suggest. I draw 26 inches.

You have enough bow.  I would try to get an arrow that weighs in the ballpark of 600 grains, and use a sharp sturdy broadhead.  Moose aren't that hard to bring down, if you hit it where you are supposed to.

What he said. Use what you're comfortable with. They aren't as tough as you may think. Just big. Good eatin too. Goog Luck on your hunt!
