I have not seen much less used the call mentioned above, so I really am no help. Each call has its own characteristics on how it best performs. Videos are always better--because hand positioning is often crucial to get the sounds you are after, and when you can see the hand positioning--it makes it easier to manipulate any call, not just Snow calls.
As for the Snow calls subject, I use several. On windy conditions or when they are way far off, I use Tim Grounds Snow call, it is super loud, but really more suited as a Speck call in my thinking than a Snow call. But it has the loudness that no other call has come close to, and does the job when loudness is needed. I use Haydels snow calls for the feeder "hohooohohooo" sounds, a great way for inexperienced hunters to partake--just doing the feeder call once they are within 200 yds. But my go to calls are Grounds Half Breeds which I have tuned to sound like an old Snow and a young Snow.
I know there are some newer calls on the market, but what I have works, so I have not felt the need to explore the newer stuff, thus I'm not saying they are bad or good, but I just do not know.
