If I could make a suggestion, you'll be much happier with the Mojo from River Valley Game Calls. It can be found at all Gander Mt.s or online at
www.rivervalleygamecalls.com . They work very well when wet with the carbon striker (included) which can also be used for the fall kee kee and kee kee run and it also comes with a hickory striker for a different sound when dry. Check them out.
Now between the two you mentioned, probably the Primo's...but they take too much preparation and scratching the glass compared to the MOJO.
