RE: Machined vs. cast risers
The Maverick does not have a cast riser, it has a forged machined riser and is one of their best selling bows. The die cast risers start on the action series bows with the Striker wich I think is thier cheapest adult bow.
Machined risers are stronger and straiter than cast, they are also more uniform in the over all quality of the metal. That does not mean a bow with a cast riser will not shoot well or take deer. My buddy has one the old mavericks with a die cast riser and does very well with it. But it heavy, loud and vibrates like mad when you shoot it. I don't know it that has anything to do with the riser material though.
