As far as shimano goes the old triton game reels seem to be the only reels that can handle a bit of punishment in the shimano range the rest are rubbish i've owned most at one time or another and blown the guts out of every single one.
If i had to choose i'd lean towards dawai which i use a fair bit as they only implode twice a year instead of four times a year like that shimano rubbish but if you want something that can handle aussie fish and weather a bit longer i'd advise you look at accurate reels they seem very good so far but the only reel that lasts the test of time is the good old alvey you can run them over with car and they still don't miss a beat although there about as user frendly as a lion with rabies running around seaworld.
