Baron,
Shad fishing is so hit or miss at this time of the year when water temps keep fluctuating and flow keeps dropping that further hindering your chances as a novice shad angler puts you at an extreme disadvantage. I recommend learning when and where to find them, when they are most vulnerable (time of day, month, temp, flow etc) at a given location, and do this with a spinning rod. Once you know the ropes, then switch to a fly rod if that’s your real desire. May is more predictable, but anglers usually (in general) go farther north then. I say in general because I once had a super day in Riegelsville from a boat on Memorial Day weekend. We were the only boat on the water.
