Some great information, but slightly manufacturer-biased, from City Theatrical, in this PDF.
Apollo Stackable. I requested stackable top hats in my big inventory purchase but unfortunately didn't pay close attention to the difference between the Apollo and City products and we went with the cheapest bidder (which happened to be City). What's wrong? Well the "flange" part of the top hat that slides into the gel frame to hold it in place is round on the City Stacker. The Apollo is square like a gel frame. This makes it both harder to slide the city into the slot, harder to get it to seat correctly, harder to get it out again later. The Apollo version just slides in and out like a color frame. I've dropped one City top hat because although the sides were in the slots of the instrument, the top hat twisted a little and the hat just slid out the bottom. Other times I've gotten them all placed then gone down to look at the grid and realized multiple top hats were not seated correctly and on the verge of falling out the bottom. Buy the Apollo version! I think we saved about $1 each buying the City product... Not worth it.

Apollo Tapered Top Hats
Interesting to note that the article seems to indicate Half-Hats are preferred over full hats, in almost every application.
[user]gafftaper[/user], you have affixed 1/16" safety cables to all of your accessories, haven't you?
Another negative to the City Stackable top hat is there is no pre-cut safety cable hole (Apollo has one). Furthermore that round flange is so narrow there really is no place to put the safety cable without drilling a hole out in the round hat part of the top hat which is equally problematic.
For those who are new around here and might be suspicious I am not an employee of Apollo or an Apollo dealer... although I do like their gum.
Tophat, allowing for greater savings and higher stacks!
Ya know, sometimes you have to let the products you make stand on their own. The best marketing is from satisfied users.
(Now, how many pounds of gum is this gonna cost me? )
One thing I don't see in the photos is a flange on the Apollo unit that prevents them jamming together, which seems to be a key feature of the City Theatrical unit. What happens when you stack a bunch and then push down on the stack (inevitable in real-world use)? Do they jam?
point Steve and I don't know the answer. The other thing that City does is there is a sort of VERY thin felt-like liner on the inside of the top hat... probably more like sprayed on fuzz than felt. It's obviously there to prevent sticking between hats.
Do you have anything like that in your hat Keith?
It's called "flocking".
From the CTI PDF cited:
"...the Top Hats themselves can contribute to this problem if the inside of the Top Hat cylinder is reflective. CTI takes steps to prevent this by coating the inside of the Top Hats with a material that we call flocking to help absorb the bounce from inside the top hat cylinder. Flocking is a furry, black, flameproof material that is applied in a painting process in our factory to the inside of the top hat cylinder, and when the light beams strike it, the light beams are trapped in the flocking and don’t reflect as readily outside of the Top Hat."
The Apollo description says "Tabbed and flocked for easy separation", which would lead one to think that's the primary reason is for its existence.
Didn't your parents have flocked wallpaper (most likely a fleur-de-lis pattern), in their living room? I'm sure you've seen "Snow in a Can" for use at Christmas. I never liked it; thought it to be a pretty flocked-up idea.
I would like to nominate this post for worst joke of the week.
The Apollo Tapered Top Hats have a black flocked inner surface to eliminate any reflected light leaving the fixture, while sporting four steel 'tabs' inside the tube. These four tabs allow the Tapered Top hats to be stacked, while allowing easy seperation when called upon for service. See attached photo of one of the cute little tabs-
