What's yer drawlength?
After reading your other thread I think that the strength of the limbs is possibly outweighing the strength of the take down systems available.
If you're drawing 29 or less, you may want to think about a 60" 1-piece bow. Yes, I know the shipping to Oz is a bugger (I had the same issue before I moved here from England) but a 1-piece of less than 62" really isn't a problem to fly with & it's under the maximum shipping length for the post.
M'self, I used to shoot a Pronghorn 1-piece. 60" & 86# at my draw. Man, I battered & abused the heck out of that thing. I used to shoot several hundred arrows a week & many 3-D & field tournaments of 3 shots at 40 targets with no problem at all. It's still going strong now, 4 years later. It was 3 years old when I bought it.
You can occasionally find one used for around the $350-$500 (US) mark. If you buy new, Herb Meland is an awesome guy to deal with.
Performace wise IT was certanly up there witthe best of 'em. I don't have figures because I never chrono'd it, but shooting a pine shaft with a 125gn point, I didn't have to aim any differently from 15 to 40 meters. It was really smooth out o 29", but stacked a bit at my 30" draw. I really should've had a 62 or 64"
