Browns,- tremains platinum line of macs are actually natural intergrades, (as he will agree), so a totally different kettle of fish altogether so can not even be compared to a true blonde mac.
I tend to disagree with what you say about the blondes. Light coloured macs can be found all over their range. One of the lightest and largest macs ive seen,(over 5 feet), was from the hinterland behind caboolture in s/e qld, but i would not call it a blonde. To me the true blonde macs are the cooktown form as its not just colour but pattern as well that makes them what they are. This is the form that blonde mac was named for, but these days anyone with light coloured macs from anywhere in their range call them blondes,(hell alot of what get called blondes arnt even very light). Not all cooktown macs are blondes either.
