The blue one in the 2 pack is the Ghost cut and IMHO one of the easiest diaphragm calls to learn.

The price for the 2PK you are looking at is a really good price at walmart they cost around $12.50 or so for just one call.

I have owned both and I could do nothing with the other call in the 2 pack you are looking at but the blue one with the ghost cut was rather user friendly but it takes quit a bit of air to get good sound out of this call. But I still have 2 and really like them!!!

I recently purchased a Tom Teasers Cracked Corn ghost cut and it doesn't take no where near as much air to make the call sound really good which is a plus when you are getting up close and personal with a tom.

The Tom Teasers mouth calls are $9.00 each and shipping is $5.95 no matter how many items you order. They have excellent pot calls with the Aluminum being my favorite. Check them out at www.tomteasers.com Some of the calls are pricey when you conmpare to wal-mart or the low priced lines of turkey calls but it is more than worth it.

I have 2 slate, 2 glass and 1 aluminum pot call, 3 diaphragm calls and plan to order more because everything I have ordered has been top notch and worked great for me.
