Troll is actually cheaper than Orc given the higher BODY and STRENGTH it gives. Troll is a huge target. Add chrome all over, and you may start hearing "Holy crud, Fred, grab the anti-tank rounds!" Not to mention that you'll get targeted by every opponent.
Check to see how your GM rules cyberlimb armor, and whether or not they allow it to stack with orthoskin, dermal plating, and worn armor. (It does by 4E RAW.)
19 from cyberlimb, 3 from orthoskin, 2 from bulky dermal deposits, 14/12 SWAT Armor & helm, 6/2 FFBA, 2/4 PPP no helm = Total 46/42, not including dual-wielding ballistic shields (and whatever I forgot)
Info below copy/pasted from this thread:
http://forums.shadowrun4.com/index.php?topic=3724.msg48612#msg48612Max armor is 19 from obvious cyberlimbs and 17 from synthetic.
Standard - Essence cost 6.25 (can't be done).
Alpha - Essence cost 5.0
Delta - Essence 3.125 (maybe in somebody's campaign...)
Customized Obvious:
Full arm will have 7 capacity left.
Full leg will have 12 capacity left.
Torso will have 2 capacity left.
Skull will have 0 capacity left.
Customized cyberlimbs can be increased to natural attribute maximum. If you have strength or agility augmented to above natural maximum, you still have to enhance the cyberlimbs or those stats effectively decrease. The elf street samurai dual-wielding full automatics can fit cyberarm gyromount [4] and has [3] left to buy whatever else he wants in his arms - i.e. agility.
Customized synthetic, almost nothing else can be added:
Full arm - 0 capacity left
Full leg - 2 capacity left
Torso - 1 capacity left
