Pht you know that the choice of hitlocations is already in the tt called TC. In my first games I used them as welcome additional -1 for to hit always ignoring the +3 to go for the kill.
It was the Legionaire and its RAC 5, that changed that.
Its high risk high gain.
you're right: I did forget about that, and here it is:
Total Warfare, Pg 143 said:
TARGETING COMPUTER To make an attack using the targeting computer, follow all standard rules for weapons of that type, but modify the to-hit number for any attacks using the unit’s weapon by –1 (see the appropriate Weapons and Equipment table to determine which weapons can be used with a targeting computer).
The controlling player may use the targeting computer to attempt to attack a specific hit location on an active unit. To do so, an attacking unit ignores the standard –1 to-hit modifier for the targeting computer and uses the Aimed Shots rule (see p. 110), but applies an additional +3 to-hit modifier. The target need not be immobile when using a targeting computer to make such an aimed shot; if the target is not immobile, then the –4 to-hit modifier for an attack against an immobile target does not apply. An attacker cannot target a ’Mech’s head when making an aimed shot with a targeting computer.
If using a targeting computer to make an aimed shot against an immobile target, apply an additional –1 modifier (representing the targeting computer) to the –4 immobile target modifier. All other rules for an aimed shot remain the same.
LB-X Autocannons: When firing cluster munitions, LB-X autocannons lose the benefits of the firing unit’s targeting computer.
Pulse and Rapid-Fire Weapons: Pulse and rapid-fire weapons may not use a targeting computer to make an aimed shot, unless a rapid-fire weapon is fi ring a single shot, in which case it can make an aimed shot as described above).
And here's the aimed shot rule that's referenced:
Total Warfare, Pg 110 said:
Aimed Shots: Players may make aimed shots against units that are shut down or whose warrior is unconscious, using any weapons other than missile launchers and LB-X autocannon firing cluster munitions. When firing on an immobile ’Mech, the attacking player can make an aimed shot by naming a target location. Against any hit location except the head, the player makes the to-hit roll using the standard –4 to-hit modifier for firing at an immobile target.
If the attack is successful, the player rolls again. On a result of 6, 7 or 8, his shot hits the designated location. For any other result, the player rolls normally on the ’Mech Hit Location Table. (This roll may still result in the attack striking the desired location.)
If the attacker is taking an aimed shot at the target ’Mech’s head, modify the to-hit number by +3 rather than the normal –4. If the shot hits, the player rolls 2D6. On a result of 6, 7 or 8, the shot hits the head. For any other result, roll normally on the ’Mech Hit Location Table.
Players cannot use the Aimed Shots rule to make physical attacks.
Targeting Computer: A warrior can use a targeting computer to make an aimed shot against an active target (see Targeting Computer, p. 143). If using a targeting computer to make an aimed shot against an immobile target, the player adds a –1 modifier (representing the targeting computer) to the –4 immobile target modifier. (All other rules remain the same.)

High risk indeed, especially if one is trying to make a headshot vs a mobile 'mech.
I haven't worked the math out, but it seems that your chances of missing totally offset the ability to pick a location when using a targeting computer - I imagine the total number of weapons hitting any given location are not going to be that much higher percentage wise than aiming center of mass while not using an advanced targeting computer... and TC's are obscenely heavy and large - not only are they computer hardware, but extra hardware to help the individual weapons converge... and only a few mechs could use them, if a sane mechlab set of restrictions were enforced.
I'll have to edit this into my post on weapons convergence... It will be interesting to see the reaction of the pro-fps/shooter crowd to this.
