I haven't been up since August 4th as my son was up there for a week with his friends. Reports I have heard is that Frazer is still going strong with pockets of excellent fishing. If I were up there this weekend, I would still focus on the 17-22 feet areas with a Lindy Crawler/Leech presentation. I have really learned from this board to trust electronics and move on if you don't mark too many fish.
I personally think the tube diameter is a bit small, when you laod it up if your balance is off some waves can be dicey on a boat with smaller tubes. Crestliner makes a good boat though. What kind of motor?
This past week I have spent quite a bit of time on both Frazer and Big Bay. I have been finding good action in both areas with both leadcore and lindy/crawler presentations. Depth has varied depending on the time of day I have been out. Anywhere from 18-38' of water. We even picked up some bonus large bluegills on the crawlers in about 25' of water in Frazer Bay. Plenty of eater eyes so we let them go but was some fun action for the kids. Also buzzed up to the west end a couple days ago for awhile and found a few nice walleyes on the deeper weed edges. Found a couple areas where the graph was loaded with small perch/baitfish and a #9 jigging rap did the trick. Good luck out there!
