I wore out a couple of Senco sfn2's in a prior life, 15 gauge, my beef with them was that the thin oak trim was prone to cracking with them. Went to a Hitachi with 16 gauge, forgot the model # but the straight rather than angled and got along a lot better. Granted, you can not flatten a warped piece of trim, but it not easy to remove. And I also found the Hitachi to be much more trouble free. Of course the Sencos were older models.
