I do remember the D&D combat wheel. It was both cool and useful.
And, I don't think I've ever seen one done for CT. I think it would be difficult, given all the weapons.
What I do in CT (and, really, just about any rpg play) is make a separate sheet of paper for each piece of equipment the character is carrying instead of listing that equipment on the character's sheet.
This is collected into the player's notebook/3-ring binder/manilla folder/whatever.
I do this for a number of reasons (as I said...not just for CT, but for all rpgs we play).
First, I find that players sometimes don't have a handle on just how much equipment their character is carrying. With each piece having its own sheet of notebook paper, there's something tangible to that--something that gives the player a feeling for all the stuff he has.
Second, it makes it very easy for characters to exchange equipment. When I hear, "I'm giving my pistol to so-and-so, keeping my SMG," I'll reply. "OK. Give him the sheet, then."
Third, there's no arguments about who has what. If you've got it, it's in your player notebook. If it's not in there, you don't have it.
Fourth, it also makes it easy to customize equipment. If a particular weapon uses non-standard ammo or has slightly different stats for some reason, just mark it on the sheet. Whammo. Good-to-go.
And, fifth, I address your concern about having to read tables from CT in a game. In my game, we never refer to the combat tables because we don't have to. Each piece of equipment has its particular stats written on its sheet. The player will usually ask what the enemy's armor is (and sometimes, I won't tell them, and just do that adjustment to the die roll myself), and then simply look at their sheet--good-to-go, knowing all their modifiers for the combat.
It makes combat in CT very easy--not table looking at all.
