Definately get a lower targeting scope, maybe 225 for as close to 1/1 as possible, regular damage from peren will od possible AS damage at that level.
Touch of gripper instead of right arm symb, damage add damage add damage add. Also keeper's vitality would be more effective vs Pump damage from AC's than the duck explosion mod on waist. That or simply getting Projectile AC's. My 25 ( now 30) agent used a 115 agility waist implant permanently though and it is nice to have that stat for trickle and gear.
Body dev chest implant and totw damage shoulder would probly also be more beneficial to your setup unless you wanna keep the full evades thing going. (only lose a little health from body dev over health cluster, and if trox its in fact more health).
Use as high CSS as you can possible equip don't worry about OE at all. You will likely get armor at 50% oe but your AC's won't be hurt too badly and you would only lose like 1 point of aao. Evades and wep boosts and inits would be kept so major+++ there.
Scent sensor for trickle. Endorphin factory and FP in a fixers treatment implant dis clinic. Comm relay wouldn't hurt either
perfectly cut black opal rings times two if thats the right ones for +aad.
If you do go trader you can cast the drains from conceal and others won't be able to do anything about it until after they are drained no matter the cast time. Only one drain though so use the top 90% check you could use.
ql 90 implants are possible on a 15 froob, as an agent with research and NS you can do somewhere just over 100 I think without pushing yourself too hard. If lya's drops on the holloween patch again get the shoulders and sleeves and you can do 110
CSS over ofab sleeves if you can use kizzers thanks to it. I think you can get sharp obj from 2 ai perks at that level as well as sharp obj hud manual and every bit of trickle you can do (lya sangi shoulders when they come out again)
6slot is doable but it sucks ass trying to work with 2 outside buffers and nano stimmers at the same time you are twinking as well as a fixer to keep that NCU perk running on you. After that compiler would be nice for the NR and inits ofc which you could probly spam general shop heal quite effectively for that added push.
Simians bracelets for damage add over jobe bracers maybe or ofc the totw bracelets of amplified sound for skill.
All the aad will probly help you a ton more if you can use TIM scope and go about 50% or lower aggdef. Just test it out since the aggdef will help a ton vs those traders too.
OMG so much typing lol. Anyways this is what I would do as a start
and hopefully you like your twink.
