You got a couple good calls there. I have the ol" betsy and I really like the smooth mellow tones of this call. The diamond yelper is another good one even though I prefer their stacked frame calls. I know it is tough to try to learn this sport via the internet but you are blessed to live in a time of readily avaiable information. You should've tried to get started twenty years ago when oldtimers would rub out any turkey tracks they found to keep others off their birds. I still catch myself doing that from time to time. Try locating videos, many callmakers now sell videos with good instructions on how to use their calls.
If I could give you some advice don't think you have to immediately learn all the high fallutin competition type calls. Many a bird has met his fate responding to simple clucks and purrs. Calling is only a small part of what it takes to be successful. If I had to rate it I would say 80% woodsmanship (being in the right place, knowing how to approach a bird) and 20% calling skill (more knowing when not to call than fancy calling). JMHO
