Equipment looks great, just stick to it. As for slayer master I think Duradel would be best. Use your cannon when possible, on Dagganoths, Kalphites, Aberrants and Bloodvelds for instance. Use a combat familiar when you're in a multicombat zone.. A BoB shouldn't really be necessary. Oh.. And always use super sets and superhuman strength (so bring a few prayer potions), you could of course use Piety instead but that would raise the cost due to a lot more prayer potions used.
