Needwood is heavily pressured, but if your inflatable kayak will get you to spots bank fishing can't access, such as the bluff walls on the far side, you should get some fish. It's not too big for you to paddle around too. What are you throwing? A small paddletail always works there as a search bait, or a craw along laydowns. In the spring, I see lots of bass staging for spawning around this area: https://maps.app.goo.gl/PEtDGRkCo4ur6Y5U8 Lots of large boulders and sunken wood. Be prepared to lose some lures.
Little Seneca Lake is huge, and if you're in an inflatable and there's wind fetch, it'll take you forever to paddle back. Lake Whetstone is a little lake out by Lakeforest Mall, a perfect size for an inflatable too. I used to fish there with my kids and walk along the pathway and I would see kayakers in there. There are some quality bass in there.
