Kc......IMO your on the right path....I would go with the fingerling for the spring...Personally I like to match the hatch....The bait tends to be a little smaller in the spring, so I try to run a little bit smaller bait. Now If I happen to see big bait , I will switch over...Early last summer I stopped getting quality bites on regular size spoons. I checked the fish I caught and noticed all the bait in their stomachs was huge. I switched to Mags and the action continued throughout the summer.....
Good luck this season ........
