I just recieved my order from Haydels Calls and man are they impressive. I got the W-81 and WW-90 and they are spot on. I have never heard or blown a call that mimics a wood duck better than these two. I can't wait to try them this weekend and the weather looks perfect. If you haven't heard em before go to their website, they have audio clips of each call. You can get a pack with both calls for like $16 bucks!!! I've been practicing with recordings I got on line and I am pumped for Saturday!!!!
