I do not believe Iowa has a minimum weight. I've heard various numbers float around in conversations ranging between 31-40# but I've looked through the DNR regs and can't find any actual requirement. Fully agree with Shovel about the cut on contact broadheads, they're a practical requirement. Forget Muzzys and the like. Shovel's a bit of a legend and uses stone and forged type tips mountain man style but many guys use heads like Magnus, Zwickey, Woodsmans, etc. Also, I do <u>NOT</u> want to talk you out of using cedar or other wood shafts before you even get started because it can all be part of the experience but to be honest up front, a lot of the crossover trad guys I've dealt with including myself, use carbons. Beman 500's or similar to be exact and I add weight tubes into the arrow shafts to get a nice heavy arrow. Total personal decision only you can make. As far as point/head weight, forget 100 grains, in traditional you're looking more at 125, 150, and on up. Some people go well on up past that to give the arrow the necessary weight. In other words, there's multiple ways to add weight to arrows for use in traditional type bows.
