Torx, is a horrible design, especially the security kind with the pin in the middle,
There are too many sizes to close together t25, t27, t30, is an example, t8, t10. t15 is another, it was some dumb engineers idea for the auto sector, because he or they felt things were to simple and didn't like the fact you used to be able to service a vechicle with a blade screwdriver, a crescent wrench, a pair of pliers and a simple 9pc socket set and a hammer.
In addtion to the size issue, the smaller sizes don't handle torque well, above t30 not as much of a problem,
as stated above they gum up with **** and then are hard to clean, especially the security ones,
the list can go on and on,
