While it's wise to not ignore hull entirely, it's also entirely possible to outfit a ship to never have shields drop in the first place.Sounds like you are running a pure shield build, have you considered a Hybrid build? This will save immensely on Power draw letting you fit some heavier weaponry.
Build your ship somewhat like a hull tank, then add a Bi-Weave that will restore rapidly. Use heat sinks or chaff to temporarily disable enemy targetting rather than shield boosters. This way the shield is soaking up damage adding to your total hit points but if it goes down you don't explode instantly. I've used this to great success during the Thargoid War enabling a Courier to spend lots of time in Combat tackling multiple Thargoids until the Ammo runs out![]()
It helps to that end to use utility slots for shield boosters (universally useful) instead of heat sinks (not necessary so long as you avoid the overcharged powerplant noob-trap and pay some mind to certain other engineering choices) or chaff (not that useful on non-small ships and limited duration).
Guardian Shield Reinforcement Packages in particular enable turning any ship in the game into an effective shield tank. At size 5 and above (with the relative worth vs a GSRP in mind), SCBs also play a significant role.
