I am a miner. That is what I do. The following are my personal perspectives. Use or lose these as you see fit.
Mining whilst aligned makes absolutely no difference to your warp out time. You have to be physically moving whilst aligned. And the only way to be moving and still be within range of an ice block for long enough is to fit the Higgs anchor. I have never fitted one. Don’t see the point.
A more old school option for you is to orbit the ice as you are mining. Yes, you are moving but you are not aligned. So again, it makes no difference to warp out time. However, it simply makes you a moving target, and takes just a tiny bit longer for someone to reach and lock you. Orbit at 5-7.5 km distance of ice and perhaps every time you unload, also fly back to a different ice block.
The scanner is redundant on ice simply because each block is a minimum 90,000 m3. At that size, it will take you 7/8 full ore holds to blow up. Plus, if you keep moving blocks anyway, that is two reasons why you will never need to know how much ice is left in real time. On average, you will never run out. Just dump it.
Next thing, I use procurer or skiff because they are the only ships you can fit for max yield without being fail fit. (Try putting T2 harvesters and max number of upgrades onto simulated covetor and retriever and you will see the point with respect to their tank.) On that basis, take advantage of the naturally high tank and always fit an ice rig. No real point in targeting ice if you don’t. And fit the T2 harvesters. Same reason. Plus, even with higher cost T2s, the time it will take you to mine your replacement value is maybe only 90 to 120 minutes on ice? So, shrug it off, learn the lessons. Keep moving.
That leaves the shield rigs and mods. I like resists as opposed to core or strength. And the classic resists against catalysts and/or ganks is EM and thermal. If you were keeping the scanner, I would swap one core rig for a thermal rig and replace one of the adaptive mods with an em field II . Or vice versa. But, if you are dumping scanner, then you have options. Maybe still keep the two core rigs but have triplet active hardeners in the mids instead ie thermal, EM and one adaptive. Or do the rig/mod EM/thermal thing and keep two adaptives. Your choice.
