I started out trying to use the Ceiltile staples, but I had two major problems with them:

1. The chiseled points tended to split the wood instead of punch though like the flat tip staples.

2. The chiseled point have opposite orientation on each leg of the staple, and I found this was causing the staple to blow out the side of the form.

I used 9/16" staples with flat tips into OSB forms and only had problems at those concave areas near the stems. For those areas, I clamped the best I could.
