I had a problem embracing the Troll Grunt as a fun concept to play. You hang out and wait for the fire fight all night and when its over you get stitched back up waiting for the next. Having the Troll a charisma using as mentioned last post could work well. Maybe you want to go a more Troll bouncer type than if he was being sponsered by a corp to be a living cyber ad. Troll bouncer would be tough, physically imposing but with analytical and social skill sets. The player would get a chance to plug into a run more with knowledge sets on entertainment, street, and maybe some shadow community.
Contacts write themselves from dancers, bartenders, clubbers, fixers, street gangs, poparatzzi, BTL dealers, joygirls & boys, posers, nova rich, DJ's, entertainers, experienced shadowrunner, celebrities, maybe law enforcement and organized crime individuals. Going with that a club wants a imposing but not scary doorman.
So he will polish them up a bit with maybe cosmetic surgery, a good secure commlink, internal taser/ shock weapon, synthacardium still works, display link for the comm, vision magnification and lowlight, Reaction Enhancers are good, smartlink, muscle aug can go big here, tox screen or toxin remover of any stripe, and keep bonelacing if you think his sponser will want him doing some heavy lifting security wise.
Skills should have a good close in fighting, a good cut down shotgun w/ smartgun link, athletics, perception, maybe a extendable baton, but also add Negotation (beef his opposition skill to being fast talked), Et(Street/Club/or Corp) depending on where he works, emergency first aid, and keep the Intimidation beefed up. He doesn't need the ride as much, get by on a min driving. When people need his services they will find him a way there. Knowledge skills may be in the entertainment biz, club scene, organized crime, area the club is at, pick a music, btl markets, smuggling tricks (sneaking things and people in) and security procedures (VIP).
Having him uneducated fails here and I was having a hard time thinking anyone would put half a mil of gear in someone who couldn't read to begin with but everyone has a story right. Day Job and In Debt work good as he is working his way out of debt for the Cyber. He may even want to break into the business as a actor or Troll model. He could see himself as the evil villian in the next Neil the orc barbarian flick. He could also have a rival or enemy easily enough, maybe defending a contact at the bar or his boss.
I obviously ran off the rails brainstorming on Bash but I think that was the part missing most in the character. Dice pools aside it was a immediately forgettable character. Just have a little more fun in concept. Make B-Bash the gonna claw his way up out and into the lights Troll. I have seen to many industrial refrigerator sized bullet magnets for this life time. Only meant as a helpful suggestion and I do hope it was at least a little helpful.
