if you absolutely HAVE TO play as sin, the only kind of sin I'd be interested in watching is a batstriker, she's fun to play if ur not afraid of skillswitching and can do well with cheap gear
also be aware that some skills are bugged atm and will be fixed in a couple days, for example deathgaze and famine
also try to focus on enjoying yourself instead of obsessing over getting all charms asap, it will make for a more pleasing experience for both you and your viewers
