I reckon Redbull661 needs to throw a hard nose bar into the mix?!?..We all know they are slow and rob power /create massive drag/overheat/stretch chains/can't plunge cut etc etc...
I think it would be interesting to find out just how slow are hardnose bars? and Redbull661 is the man to test this yes/no?
I like me hardnose bars not for there speed racer cutty cutty stuff but the durability they offer and I think the old hard on chain's is a myth IMHO well long as you know what ya doing that is. I dress the bar when a new chain goes on and only take it off when it's used up and has no more hand files left in it (unless I smoke the chain by hitting a rock or some chit)..
But yeah just how crap are the old chitty hard nose bars next to these high dollar porcelain bearing low friction teflon coated bars?...
I like the older Oregon hardnose bars myself the radius on the nose is on the money! Stihl hardnose bars the radius on the nose is well odd? just meh.. All IMHO

A vid nothing special 088 hardnose bar .404 RS 7pin timber is Red Ironbark ...I have tried 8pin on the 088 but works way too hard and gets very hot and almost melts the top cover off! and if the dogs touch it just bogs! needs some more bananas to run a 8pin in Red Ironbark.....
