Glad to hear your getting your dad back into it. I am from Ohio and the bow used mostly here is the Horton. I shot my first Horton super mag for twelve years with only one string change. My new Horton from last year is the supper max 175 and I love it just as much. Horton is the main bow around here but it has had a long hold in Ohio since Ohio has had the CB since the late seventys. Alot of us on here shoot the horton and the Excaliburs and all seem to be happy. The Excalibur would be my second option right after my Horton. I would recomend though that you take your dad to a proshop and let him shoot all the top brands like Tenpoint, Horton and Excalibur before you make your choice. As far as arrows go it would all depend on your old ones. I know the diameter is important as to keep the arrow in the barrel corectly as you shot it, a small shaft would be to low in it and a fat one would sit up to high in it. Also Horton advises against I believe anything less than 430 grains, you get to light of an arrow and you can damage the powerfull limbs. In CB you dont have the relation like you do with arrows and bow weight and draw weight like you do with a long bow. I think most of us on here just use the bows brand of arrows. I have always used the horton line myself, that I think they were 2219 but for the past couple of years I have used the horton carbons. Good luck!!
