No reason you can't shoot and enjoy both, but remember they are two different pieces of equipment--a stock car and dragster are both cars, and have some similarities, but are also totally different in ways.

Rick Welch is one heck of a shot, no doubt (not much of a talker though), but his methods may not work the best for everyone--the same goes for Larry Yein, Bill Leslie, Bob Wesley, Byron Ferguson, G. Fred Asbell, etc. Most all will have the same basic rules, but all have their own styles. The exact same anchor will not work the same for everyone, as different people have different facial structures--an anchor that puts the arrow right under my eye might be way off for you. I'm not saying Rick's video won't help, and it could be right on for you, but if it's not don't get frustrated and think you don't have any hope--just try something different. There is no one style that will work best for everyone.

Sag., out of curiosity, do you know which world shoots Rick has competed in? I know he's smoked the Lofton Classic several times in recurve, longbow, and selfbow (quite a feat) and they refer to it as a "world championship", but it's not quite that big (nowhere near it). Heck, I have come in 6th or 9th in longbow there, and I'm a far cry from 9th best in the world.
Same went for the Howard Hill shoot back when it was going on--dang good shoot, lots of dang good shooters there, but the competition itself could in no way be sactioned as a true world championship.
