Rob, I new that semi- retirement thing would work out just fine for you.
These aren't as fancy as Jon's but were fun messing with and are light enough to cast with a 7wt fly rod and heavy enough for a light spinning rod. They have worked quite well on area largemouths. The one pictured is a synthetic stopper from a wine bottle. They come in purple, yellow, red, green, etc. and are a nice bonus if you enjoy an occasional glass of wine. I have a nice stock of them as well as corks . If there is a winery in your area you may be able to get a deal on the stoppers as they surely order bulk.
