Need a Quick Response on Wielding Two Implements

[Kaledor]

I know there is a feat for dual implement wielding. It allows you to add the enhancement bonus of your off-hand to damage. But what if I don't have the feat?

I am assuming I can still wield two implements and decide which one I am currently using to cast my spells through...

Question:
If both implements are magical, do I:
1) get the property bonus from both (let say one add +2 to fire damage and one is +1 AC)?
2) get the crit bonus from both (one gives a +d6 the other a +d8)?




PS.
Our group is currently voting and says:
1) "yes". magic item properties are always "active"
2) there is at least one "yes" vote, and he is using the idea that most implements are keyed as "off-hand" anyways and you still get their crit bonus when you cast. For instance if your mage wielded a sword (non-implement) and a tome (off-hand implement), he would get the tome's bonuses...

You can only use one for a given attack. So when the attack is made, you pick which one is in use. Most powers say things like "when using this implement to attack you get X".

I believe static powers, like +1 AC when wielding, would work as long as you had the implement in hand (or whatever).

You can use both, but if they have powers or properties that say 'When you attack with this _____' then you can only use one. That includes enhancement bonuses, and critical damage, which only apply when you attack with it.

There is a feat that allows you to add a second implement's enhancement bonus to damage, but you're still only attacking with one.
