Hmm... I have thought about the benefits of the Aussi Halyard before, I have seen it at my friendly local sailboat shop for $100 plus and I am confused about the promised benefits...
2/3 or 66% of reduced mast compression - How???
Easier tacking - Why is that - with the purchase in place there will be even more lines for the jib to get stuck in???
Better mast rotation and more consistent bend - Hmmm... it pulls from the same fixed points so why will there an improvement.
I have read about some people relocating the lower block to the front of the mast... That makes sense to me in terms of mast bend.
I have also heard of installing a fairlead or a clip to keep the purchase or wire close to the mast - that would help the jib to tack with more ease.
Why would it be a good idea to replace the wire part of the halyard with a line? What is the benefit of placing the double block far up on the mast?

Thanks,

Patrick
