My bad. I thought the d-pad was just meant to select your weapon and not hold it down while aiming and let go of the d-pad to fire the weapon. All the article said was that the d-pad was for weapon usage and I took that it was just for selecting weapons. It did reference the first article to it's credit which at the time I didn't go back and read. If you're making a big point about the d-pad dealio you should have quickly explained what the d-pad did right there and then tho.

It does seems like quite a strange system. So I can see why you all thought it was awkward.
Definitely the problem is they are taking the same GAmecube Zelda control system and mapping it to the wiimote instead of building a control system from the ground up for the wiimote. I did expect some of this because after all we know the game spent most of it's life as a 'Cube game and it might be too much to go back and redesign the game around a whole new control system.
Still I can think of a couple of ways to fix it.
Scheme #1: Why not make the 'b' trigger fire all the weapons. Use the d-pad to select the sword, bow or boomerang. At the same time make the help key part of the menu rather then the up direction on the d-pad. The up direction can then be used to select an additional item. The beauty here is it would be alot more comfortable using the 'b' button to fire the bow and boomerang. The downside is you have to shift back to the sword using the d-pad everytime you want to use it.
Scheme #2: Another similar scheme is to make the down direction of the d-pad the fire button for weapons and items. The other 3 directions select the weapon or item you want to use. The help button is moved to the menu screen. The thinking here is the down direction is closest to the 'A' button and you should be able to reach it pretty easily with the top of your thumb without shifting your grip. This would also give you simultaneous use of your sword because the 'b' trigger would always be used for the sword as it is now. So you could have the sword and another item at your disposal simultaneously with no need to shift your grip or select the 2nd weapon/item. Sort of a compromise between the first scheme I listed and how WindWaker is.
Scheme #3: Wiimote or nunchuk gestures are used to select weapons instead of the d-pad. Could be used in place of the d-pad weapon/item selection in schemes #1 and #2. The thinking is gestures would allow you to even more quickly switch between weapons/items. These would be simple gestures like twist the wiimote left or right to select bow or boomerang. Then use bottom direction of d-pad to fire as in the 2nd scheme above for example or you could use it conjuction with scheme #1 where the 'b' trigger is always the 'fire' button for every item/weapon including the sword. Nunchuk could also be used twisted left or right to select a weapon or item.
I think I like scheme #3 best.
The other thing I might do away with is Z-targeting. It seems there is less of a need for this as aiming, imo will prove to not as clumsy with wiimote compared to the analog stick. Or I would map the Z-targeting button to the d-pad which frees up the nunchuk button for something more useful.
