Any particular reason you built the rod? My wife is spinning only and has St. Croix Rods rated up to 2 oz. and plenty of inshore rods if there isn’t a freshwater specific on that would work.
I kinda laugh at the finess only idea. Caught sharks, AJs, Goliath grouper and a ton of other stuff with big baits on spinning gear and there wasn’t an issue. I use casting gear at times for fun, but it’s not inherently better, just user preference.
