RE: Octane rest VS Whisker B.
I have been using the Hostage Pro for 2008 season. The 2009 model has the improved bristles that should not wear out. I have to order some for my current rest.
Hostage Pro IS the best hunting rest on the market today(IMO). Here is why I think why it is the best.
1. Quiet - the rest is almost silent when pulling my bow back.
2. Tough - I dropped my bow this year and the rest came through like a champ.
3. Accurate and Consistant arrow flight
4. Allows me to be mobile and stalk
5. Zero Fletching Contact
All my bows will have Hostage Pro rest on them. Being I am just a hunter.
It's simple, Quiet, accurate and it works great!!!
EDIT
Let me add I think Aluminum arrows are quieter than carbons.
