How is speedshot trickshot speedshot enough to deal 30k? Full crit, you're looking at best, 7 + 3.2 x 4 + 7 + 3.2 x 4. That's assuming no heals, and no cooldowns, and 100% crit. Unless you're extremely lucky, this will never be enough.
I generally go Crit Snipe - Followthrough - SoS - FT - Sniper Volley - SoS - FT - Snipe - Explosive Probe - Ambush - FT - Takedown - FT.
