I use an open-reed style call for 90+% of my cow calling, and there are a LOT of folks out there that do. Mouth calls are AWESOME, but there are some things an open reed can do for you that a mouth diaphragm can't, and that's why they're my "go to" call of choice. Different reed styles, different sound boards, and different resonating "chambers" on each of the different types of open-reed calls out there will impart a different feel, ease of use, tonal quality, and versatility. Best bet is to play around with one or two different styles (wide reed vs. narrow, long tapered vs. short, etc.) and see how you like them, and how they work for you. ...if you want to pick apart a PILE of different calls on video first, consider checking out our website and take a look at the "Understanding and Using Cow Calls" video series; we go through ALL of the ins and outs of the different styles of calls so you can know what each one gives you and what you can expect.
With bugles, nothing beats a mouth diaphragm for versatility and realism for those that can blow them well, but the Primos Blue-Reed systems are a very close second as far as an "external reed" bugle goes. There are a lot of folks that like to criticize the Primos bugles, but they aren't the number one external reed bugle out there without reason; easy to use, great versatility, and great realism if you know how to use them properly. ...again, we've got videos on all the different types of bugles out there as well if you want to check them out.
Don't be discouraged if RIGHT NOW you have trouble with mouth diaphragm calls. In time, and with some instruction, I'll bet you can learn them, use them well, and overcome your gag reflex. However, in the meantime, and to increase your diversity of calling, jump on an open-reed style cow call or external reed bugle and start playing around with them. They're awesome!
