In my opinion, 16.9" to 27…

In my opinion, 16.9" to 27.55" (43 to 70 cm) is too tight on the lower end....maybe consider using round numbers and go with 45 cm to 75 cm....easier to remember, and gives a slightly larger fish able to keep (up to 45 cm or 17.7")...still protects breeders and gets the job done. If someone really wants to keep a trophy, its gotta be 75 cm or 29.52" to keep, basically a 30" fish, a true trophy.
In a few years, it may be hard to find a 14" to 16.9" fish.....as the whole side of the lake will be looking for the same size fish.....open up the keeper slot a hair, unless you want people keeping 12" walleye.
I completly agree with protecting the breeders, I've seen people keep 23, 24, 25" walleyes for no other reason than bragging rights of the biggest fish in the cleaning house.....protect those fish, but don't tighten up the reasonable keeper slot too much. Thank you!
