I can recommend the old Milo Luxury which has the top 3 telescopic with the rest being take apart . . . mine weighs in at under 400gms and has stood the test of time and use.
That Milo sounds perfect but try finding one!The only option I have at the moment is the Daiwa ZR8 whip which is a bit pricey but looks good.I need one asap to replace a broken one so might just end up buying a ZR8.A buddy has an old Conny 8m whip,now that is a bit of class.
