SR4 Questions Options

[Thanee]

Hiyas!

Got the new Shadowrun 4th Edition (and like it so far :)), but there are some open questions, which I hope someone can clear up for me:

1) Skill Groups - Specialization - While it's clear, that you cannot specialize a Skill Group, the question still arises, whether you can specialize in one individual Skill out of a Skill Group (i.e. learn Firearms Skill Group and then take a Specialization in Pistols). Is that possible (with BP / Karma / both)?

2) Skill Groups - individual Skills - Can you pick up a Skill Group *and* raise one Skill out of it individually during character creation (i.e. learn Firearms Skill Group at 4 and then raise Pistols Skill to 5 - with BP)?

3) Skill Groups - individual Skills - When you raise an individual Skill out of a Skill Group with Karma, the Skill Group no longer exists. Is it possible to join the individual Skills together again, as a Skill Group, if you raise all the other Skills seperately, so they all have the same Rating once more?

4) Cyberware - Cyberlimb Armor - In what way does the Cyberlimb armor interact/stack with worn armor (i.e. Armor Jacket)? Does it make a difference, how many Cyberlimbs a character has? What if a character has multiple Cyberlimbs with different armor ratings? The rulebook does not go into any detail about this.

5) Cyberware - Reaction Enhancers - Do Reaction Enhancers and Wired Reflexes/Synaptic Booster work together? How about Reaction Enhancers and magically enhanced reflexes (Adept Power / Spell)?

6) Cyberware - Skillwires / Activesoft - What's the point of Rating 5 Skillwires, if there are no Rating 5 Activesofts? Anything apart from raising the maximum total Rating (2x Skillwire Rating), i.e. allowing 2x Rating 4 and 1x Rating 2 (or somesuch)?

7) Second Firearm - Dice Pool / Modifiers - When exactly do you split the dice pool, or in other words, which of the following abilities/items (hope I havn't missed any noteworthy ones) would be counted as modifiers and not split (i.e. applied to both rolls)?

7a) Skill Specialization
7b) Improved Ability (Adept Power)
7c) Reflex Recorder

That's all for now. Thank you! :)

Bye
