Well in this tough economy.. I certainly am not going to scrape the heads I have used and have parts for for 15 years or so..In leu of some bigTV marketing campaign I have shot the Thunderhead 125's on my State bow and the 85's on my western set up for flatter shooting.. I also discovererd one can hone used blades extremely sharp with a small file.. I tried this lastwinter and tested them on unfilled balloons for sharpness and the new blades out of the package are very very sharp..But contrary to popular beliefyou can hone the used ones right back to that if you practice... This will savve you about 3 bucks a head on replacemnt blades..

Last fall I shot many times and many deerwhich would have required me to replace many blades... Honing them with a file is a poor economy option... Most deer fell within sight... a few trees where also tagged..

Regardless what you shoot don't think you can kill the deer easier because some TV or Magazine add campaign... The guys that desiged the basic modular head did not make a bad choice in their design.. They all will work well if sharp and used properly..

Use your Head,,,,

No pun,
