u definetly have to go with slayer. slayer helps u train not only that .. but all ur melees and range. if u do slayer the right way u can get tons of xp an hour. on a normal day i was gettin around 1m xp total from slayer and melee stats. just getting slayere to 85 helped me max out all my melees stat, and make some decent cash back from abby whips. not to mention the 97 range i got from using the canonn for black demons and kalphites
