I know this isn't the kind of answer you're seeking, but if someone knows some intricate technique that I'm not aware of, I'd urge them to publish it. But from RS gold my own experience , I ended up being easier to just take the multi-million price tag instead of trying to squeeze every penny of gp that I could out of the deal.
I'd like to suggest Eagle kite because CLS is a suck. Aside from PvP it's pretty much nothing to offer, as it is overpowered by other weapons (usually rapier) in every circumstance. Bandos can be argued that maul has more damage and time, but CLS lets you tank with shields.
If Jad is the only thing you'll ever need to use an Eagle kites for, it's really not worth it. There are plenty of benefits that are better than CLS. My opinion of the best order to get items in: Arc Stream - cheap and the best mage ammy in game. Rapier - best melee weapon in cheap OSRS gold game. I wouldn't be using it for Jad but definitely to other uses. I already have an rapier, by the way. That's the reason I tried to choose the CLS. If it's really not much superior to a rapier in the sense of controlling I could be able to get it following the shield.
