I like most beginner bowlers are trying to get more revs.  I have been practicing with some of the tips giving out on this site.  I decide that I would give back so here is a picture of the wrist position that many people  has been describing. http://putfile.com/pic.php?pic=12/35515312245.jpg&s=x12  As far as the rest of the swing all you need to do is keep your forearm flat all the way through the swing  and pointing at your target with your shoulders square with the target.  From this position you can adjust your wrist position cocked more to the left or to the right.  Also, keeping your forearm flat(like in the picture) prevents you from the chicken wing swing flaw.  I'm not that consitent with this many revs put it's fun to tinker with.  Hope this helps.  

Anybody else feel free to post their wrist postions.
