u might be able to get away with a trio, if your lucky enough to get a world and hope that crashers dont come in a couple minutes. if u were doing trio, the tanker would definetly need ovls to account for the brewing. u should get turm before ovls btw. definitely get a fcape asap. also, bear in mind that trioing bandos is not good money at all. in order for u to make decent money & not get crashed alot, you would need ovls, turm, higher attack, and 88 or 96 summoning. gear-wise your pretty good, except switch to fcape and get rid of the bandos boots(dip in bandos spa if u need protection from the followers). lastly, spec rests are definitely worth the invent spots. and why do u need climbing boots? u should really unlock trollheim tele if thats why you have them.
