There's been lots of threads and posts about the impact of the gun laying drive (GLD), vents, and vertical stabilizer and their impact on aim time. A lot of talk, but not a lot of metrics. This came up in Triarii's Kakoa chat and I remembered that SkittlesOfSteel (now MeowsExternally) posted a helpful chart from the PC game that puts numbers to the discussion; it was halfway down the page but needs front and center placement.
Bottom line - if you can get a Vstab - that's your first choice. And get your gun rammer - so that's vstab and rammer. So now for the third piece, will it be gun laying drive or vents? Based on the graph below, vents. Because vents helps all crew skills - not just aiming.
So if your tank can mount a vstab - get vstab, rammer and vents
If your tank can't mount a vstab - get GLD, rammer and vents
So for aim time, the killer combo is vstab and vents.
