"I've gone back and forth with which one I like more," he said. "It's not like I root against one or the other because I like one more."
Straub visited Iowa on Wednesday. He attended Iowa State's junior day and several spring practices.
"My dad is from Michigan and my mom from Illinois," he said. "I was born in Illinois. I grew up watching a lot of Iowa State games. I also grew up watching Iowa games because I knew guys who went there. I really like both."
On his Iowa visit, Straub met up with former Ames' signal caller, Kyle Anderson, a walk-on with the Hawkeyes.
"It was well worth the time to go over there," Straub said. "It was great. I love the way they practice, the intensity, how the coaches are so welcoming."
Iowa recently raised its intensity in the recruitment of the 6-foot-3, 225-pound Straub.
"A couple of weeks before spring break, I started getting a lot of mail from them," he said. "It started picking up the point where I was getting it every day. Coach (Reese) Morgan invited me over for a practice. I wanted to do it. In talking with them (Wednesday), they seemed like they were somewhat interested.
"They want me in camp. Coach Morgan said they he was going to come down to the school. It's an academic visit."
Straub, who still is awaiting his first scholarship offer, said he will camp at Iowa, Iowa State and Northern Illinois. He's also hearing from South Dakota State, Missouri State, Western Illinois and Toledo.
Next month, Straub is expected to attend the Elite 11 Camp and a Nike combine in Chicago. In June, he's scheduled to be at the Sound Mind Sound Body event in Detroit.
Straub is most comfortable operating from the pocket but is a good enough athlete to make plays with his feet. His is one of the better players on the Ames High basketball team and played baseball through his sophomore year.
Iowa State is the program most familiar to Straub. He takes advantage of having a BCS school in his backyard.
"I talk with my recruiting coach at least once or twice a week," he said. "Since I'm in town, I go over to practice and talk to all of the coaches. They let me sit in on meetings. My relationship with them has been building since back in the fall when I went to their games as a visitor."
Straub is undecided about when he'll commit to a school.
"I'd like to play the season out and see what happens but if I really like a school and they offer, I could see myself making a decision before then," he said.
