Are Tormented Demons worth it off task?

I'm currently 94 slayer and having the ability to grind out so many different bosses is throwing me for a loop. (I really need to learn GWD but door/altar and 7:0 Bandos feel so awful to do). I burned through all of my slayer points to only get 2 greater demon tasks and now I have 4k arclight charges left. I figured it would be best to get the two synapses and then continue slayer so I can start doing Sire and Cerb and finish off demonic gorillas. I have 1 burning claw in 446 KC and a real spec weapon wouldn't hurt.

TL:DR : Do I do regular slayer without arclight or grind out TDs off task?
