Shrike is probably my favorite early game ship.
A simple build with Pilum, Ion Beam, 5x Tac Beam is very effective against most of enemy fleets instead of Remnants (lack of hard flux).
Then build with Sabot/Pilum, Blaster/Pulse, Ion Cannon and 4x IR is a nice support for more advanced fleets.
On such cheap ship that costs 8 DP a converted hangar with Wasp/Spark is amazing source of drone spam with PD lasers

Overall Shrike lack of anti-shield capabilities. Sabots are nice, but soon on later you will be out of ammo, so often i replace them with infinite Pilums.
Medusa with 2x Railguns/Needlers and extra pulse/blaster is more efficient, but require more DP
