Hi all,

I'm installing a pergola made from cedar and will be installing 3/4" thick slats on top of the rafters. I'm debating on whether I should purchase a narrow crown stapler to staple them up with 1/4" x 1 1/2" staples, or use my 15ga finish nailer and put two 2" nails in at opposing angles. Since it's cedar I will be using stainless steel fasteners regardless of stapler or nailer. I could use screws, but they are more expensive than staples or nails and would also take longer to install. Will staples be stonger than the finish nails? If so, would it justify the $99 staple gun? I'm open to all thoughts and suggestions.

Thanks in advance for your help!

John
