>Is there any reason to stick with the stock size? When I upgraded to new 
brakes I wanted to put in new studs and when I found out what they cost I 
considered switching to something that would be similar and more common. 
Other than possibly having to drill out the hub for different studs, are 
there any other issues? >

The head design on Pantera studs seems unique. Changing to a "more common 
design" without the locking flat may cause you some inconvenience if a stud 
loosens in its hole while you're trying to change a tire. In addition, there 
is very little clearance between the top of the studs and the rear brake 
rotor hats; this may cause contact and noise in some cars. Finally, I 
converted one car (not mine) to 911 Porsche studs, which are the next size 
larger in dia, presumably stronger and come in many lengths. And  God knows 
they are common! Just watch out for the mentioned clearance problems.
