It's an extremely interesting debate chaps, if none of you have ever cut Aussie hardwoods you would be in for a real shock. The Sydney Blue Gum that I'm cutting has a density of 850kg per cubic metre (Osage orange is 775kg per cubic metre) and although it isnt as dense as it is when it grows in its native habitat (we have a far higher rainfall than Australia - parts of the West coast of the South Island get over 20ft of rain annually) it still is incredibly hard and heavy. Then, if the choice is between the 462 and 500, regardless of the 661, I think the 500 is better suited. I want to keep one 90cc saw and this will be the 660 (for personal reasons beyond this debate) and would like a saw between it and the 261c. I'd love to get a ported one but Randy doesn't have access to them at the moment unfortunately. The 500 is also readily available here too and my friendly dealer has given me an offer of $400 off retail with an out the door price of $2100nz ($1290usd).
