So, get 1/4" staples. SYP is 'southern yellow pine', I trust? In toughness, it comes in at 470 in-lbf, a little higher than red oak at 440 in-lbf. Half inch staples in that wood isn't an easy test.
And I would add that the above hardness rating is when it is relatively new. Once it has been installed for a couple years, it gets twice as hard. (unscientific difficultly to drive a nail into old SYP)
I agree, get the 1/4" staples. There is no stapler made that will drive a
1/2" staple in that stuff.Oh, and to the O.P. : You can send that stapler to me, if you don't like it! ;-)
