I just set TDC after removing the crank pulley. Old skewl style.

The crank gear is splined on with a woodruff key, so it won't hurt to set TDC after removing the pulley. After the pulley's off, you don't need to monkey with that crank bolt. I snug the crank bolt back on there and put a 2' phillips screwdriver through the hole for sparky #1, set TDC while I CAN CHECK THE MARKS BECAUSE THE CRANK PULLEY'S NOT THERE, and bingo.

With the crank bolt snugged, you can rotate it into position, yank the belt, do what you've got to do, and the last thing you did before starting the job was set the timing. Once you have the new timing belt back on, you don't have to worry about honkin' the bolt and disturbing the timing because if you've set the tensioner, the belt will hold it in place.

I've never once needed the moroso tool. I just use an Ingersoll-Rand 1/2" impact. It actually produces 1100'lbs of torque at 169 PSI. It has ALWAYS worked, and when it can't remove a bolt, you can always turn it up high enough to break that sucker off.
