 I'm just starting 3D photography and when I mount my slides I want to
 be sure they are compatible for proper presentation.  I'll probably
 join a photoclub after I wet my feet in the 3D world.
 
 Thanks for helping out a beginner!

Well, we in the Stereoscopic Society in the UK cater for all 35mm mounting
styles! 

You see, some members who wish to retain compatibility with flat mounting
styles use the 2 x 50 x 50 style of mounting.

Others, who like to re-jig their AV shows frequently (for example) find the 41
x 101 "Realist" style of mounts convenient because they ensure that both
halves of the slide are always kept together.

So, you pay your money, and you take your choice.

It's interesting that the standard stocks of 50 x 50 mounts and projectors
have not, in fact, been overwhelmingly adopted by Stereophotographers, and I
think it's the convenience factor. 

I can store my AV shows in the minimum of physical space using "Realist"
mounts, and still pull them out for projection. With 2 x 50 x 50, it becomes
essential to store them in projector magazines. Which are bulky.

However, 2 x 50 x 50 has the advantage of automatic projection, a feature that
is only available for "Realist" mounted slides in the form of the RBT
projector (at $3000 plus, each...)

So there you are. Pros and cons everywhere!

Sorry there isn't a totally definitive answer.
