Now days, mostly Phelps.
Red Maverick
Pink Phelps
Pitch Black 1
Of those killed more elk with the Pitch Black. Not sure why.
Have 2 Riven calls I'm playing with, no idea if I'll use them yet this season.
Pro tip, if a metal domed call doesn't sound good out of the package, I flatten the dome a little in an effort to "tune" it. Not always a magic fix but often an improvement.
