Good stuff. 2 tips: a Shadow Serpentis thermal energized membraine saves you enough CPU for a DC 2 (plus very cheap at 60k ISK, saving on both the T2 membrane and IFFA DC). And noticing your orbit set was 7500m yet you were stable at 11km distance (because the target is moving and your speed is not that much higher than the BS), you could try an orbit of 5000m and see if you can at least get him under 10km to then slow it with your web, limiting the number of pacman warps and distance from gate ? I'm still only doing Tier 1 in Caracal with Heavy Missiles (94km with T1/faction ammo, though only 71km lock range, but as you entered the sites the towers were 70-74km, hopefully shooting them down early would help mitigate initial tower damage, but I would probably still need to buff the tank). The Maller has such great resist with its bonus.
Your points about the fit are right, I didn't realize the faction thermal resist is very cheap on the market. About the orbiting, same thing I must orbit a bit closer because the Maller is pretty slow. But even with the Maller's resist bonuses it's a very tough call to complete this room.
