The 6-foot-4, 175-pound Bakersfield (Calif.) 2012 point guard started his visits with an unofficial trip to nearby Fresno State.
"It was nice," Wallace said. "They showed us around campus and I liked it. I liked coach (Rodney) Terry a lot - he's really cool - and my family likes him, too. It was a good visit."
From Thursday through Saturday, Wallace was on California's campus for an official visit, which he said he enjoyed.
"It went well," said Wallace. "I was able to get answers to any questions that I had and my family got to see the campus and we all talked to the coaches.
"Coach Travis (DeCuire) and I have a connection to where I can talk to him about anything; he's sort of like a big brother. Coach (Mike) Montgomery and I got to talk and I got a feel for the program, so that's good."
Colorado: "I like their recruiting class that they're putting together, and Spencer (Dinwiddie) will be playing there this year and I know him really well. They just got Xavier (Johnson) and (Chris Jenkins) so I like that they're putting together a nice team. They're recruiting me pretty hard, too."
Oregon: "The coaching staff is pretty nice and they came down whenever they had the chance to. It seems like I could come in and play right away."
Halfway through his visit schedule, Wallace says that there remains no leader for him.
"I just want to see the other campuses and then talk it over with my family," he said. "I haven't been to Colorado or Oregon and those are pretty good schools too. But I like the schools I just visited, I like their coaches, campuses and everything."
Following Wallace's next two visits, he'll sit down with his family and see if he's able to make a decision.
"I'll compare them and if I'm ready to decide I'll do it in the early signing period and if not then I'll stick around (to the spring) and watch games this season with my dad," Wallace said.
