RE: using a crossbow?
Arthur, by not bringing up the "finer" points you give in. The release is not really mechanical. The bow must still be hand drawn! The release will only work by using your hand to draw the bow back. Besides, nobody says you cannot use a release with a recurve or longbow. I am sure it can be done, but it would partially defeat the reasons of why people use traditional equipment.
Fact is, technology keeps forging on, sometimes not for the good. Its all about money, each manufacturer trying to take a bigger share of the market, and many times fooling the public into thinking its better.
You don't know how close to starting hunting with traditional equipment I am Arthur! Its just going to take a lot of practice...been a long time since I shot a recurve and I currently have none.
