Stun Baton and Shock Gloves Options

[Johnson]

I have some interesting questions.

First -- Stun Batons
I strike an opponent with a Stun baton. I yield 2 successes more than my opponent. Damage of stun baton is 8S does the stun damage stage up to 8D

Second -- Shock Gloves
I strike an opponent with a Shock Gloves. I yield 2 successes more than my opponent. Damage of shock glove is 8S does the stun damage stage up to 8D as above.(the later would not be pertinent if successes doesn't changes shock damage)
As your physical damage also would increase (str)M stun to (str)S stun

Third -- Stun batons and Trolls
To determine TN for a Human and Troll. Human get +1 Reach(Stun Baton), Troll gets +2 Reach (Stun Baton and Nat. Reach).

Point 1 ( I believe is correct )
In saying that the Troll would either make the TN greater by +1 for human, or -1 TN for himself.

Point 2 ( This is harder game Machanics )

Human decides on either making his TN -1 or the Trolls +1. Either easier for him to hit the Troll or harder for the troll to hit him.

Troll decides on either making his TN -2 or the humans +2. Either easier for him to hit the human or harder for the human to hit him.

Point 1
This is going to be a harder longer combat as the TN are higher giving the skilled combatant the upper hand. As TN 4 or more is harder to generate on limited number D6

Point 2
All this does is make a finer line of choice, in which case the Troll is going to give the human a beating because of reach reach modifiers of 2. ( Yea I know Pole arms add a Extra reach. That would make combat totally favour Troll)

Summary.
Would it not be better to use this formula. Troll reach +2 less the Human Reach +1 giving the Troll the favour of +1 Reach and TN. This make a fair way of combat.
(To be corrected this is how the rule book explains it)
