Then try using C4 for home base. Find one with C2/C5 static. C2 have easy access to a WH with Highsec static. C5 for the yummy gasses.
Home base? is this means citadel? Must maintain and def isn’t it?
No, you dont need any structure. What I suggest you is being homeless in your home system.
Simply use boatload of alpha accounts log off in a Miasmos. Drop the gasses in a safe spot, log in using that alpha storage miasmos, take the gasses, then safely log off. Next day, your static will end up in the new C5 with its new yummy gasses. Only store the expensive gases in Miasmos.
Scan the C2 daily and when you found C2 with HS static (63-ish% chance IIRC), took out all of your gasses from miasmos and take them out the hole USING VENTURE. So you are more nimble, slippery and easier on WH masses.
This means, boatload of alphas in miasmos, huge number of bookmarks to dodge hunter, and a main toon in a venture/prospect if you omega. Oh yeah, also with another three alpha scout in Sunesis (for the scanning bonus) in case you get ambushed and podded out of the home system, so you can have find ways to get all those toons back to your home system. This way, its gonna be hard to evict you out of the hole.
You can use alpha since gas huffing skill in open to alpha, but Omega gonnabe better because the Prospect. So you can halve the time hauling stuff back to HS with double ore capacity than Venture. Also, the fact that it has covops, so you could also use C2 lowsec static WHs as hauling route, which is quite large number of them (26%ish chance). The extra gas mining yield is just a nice bonus.
But the end game for gas huffing isnt the C4, its actually C2. There is C2 with Nullsec/C6 static. Super Rare, from thousands of WH, its just 20-ish of it. You gonna need your corpsmates, structures, jump freighter to haul, list of numbers to bat phone in case you home being attacked. Totally different level.
