How many of you use the Berglas stack (Magic convention)? What do you think of it? As for me, I like it a lot, and it's the one I always use. It's also good because few magicians know it But at the same time, it can be a disadvantage.
I am currently learning Mnemonica in order to have two stacks in my arsenal. But I don't see a lot of people using the Berglas one... Any thoughts on that?

I don't see anyone using Mnemonica either...

I recently worked out that I've used a total of eight(!)stacks...some partial, some full deck...depending on the need.

Key is not to continualy jump from stack to stack; you must master one before moving on. For all the stacks I use, some are basically 'one trick only'

Chan Canasta only ever used his pet variation on the 8 Kings...

Maybe in the US, you are using the Aronson rather than the Tamariz... probably.

Nobody would like to discuss possible effects specific to the Berglas stack?

Ok, this stack does not seem to be very popular...

I think the problem is that the stack isn't very well known. The Berglas Effects book was only sold in very small quantities (200 I think), so subsequently it hasn't had the exposure the likes of the Aronson stack has. Aronson's stack has been out for so long now, countless magicians have discovered properties the author never envisioned.
The late Dennis Loomis was a champion of the stack and worked tirelessly to take it to new height.

Also, Berglas does not perform traditional card tricks like Four Ace effects, poker deals etc. He apparently dislikes spelling effects with a passion. So the stack is maybe too limited for other performers.
