What you could also do is use the mass permission copy instead of the template.
It allows you to copy the existing permissions from any forum to the new one.
Then just edit what may be unique to that forum.
It is the tab to the right when selecting permissions-Forum in the cp.

I forget about this feature sometimes myself.

For example say you have 20 forums and you want to change a setting such as "Max file attachment size"
Edit one forum with the new size then mass copy that forum to all the other forums or just a few that you select.

It saves a lot of time when you have many forums.
