I was in a tournament recently and my opponent rolled his twin-linked weapons all at once. Instead of rolling to hit with his lascannon, checking to see if he missed, then rolling another die at a second chance, he simply rolled two dice to see if he hit (still only scoring one hit if he did hit.)
It struck me as odd, but I guess the odds would still be the same and it would speed up game play a smidgen.
How do you guys and gals roll twin-linked? Am I in the minority of rolling it one and a time?
