Relatively second is air conditioning replacement (lining or vertical stability-the lining is correct in these two options, in order to prevent guns). Of course, it doesn't matter if you have a sense of air conditioning. The air conditioner is not equipped with a liner and is vertically stable.
The above choice is not one of the most popular choices of E 100. Choose according to your hobbies.
In addition to popular science, WOT has also set up a rumor for a long time, specifically explaining the use of gun control and vertical stability. Although gun control is artillery in the sense, and generally speaking, Cui Wen is dedicated to light and moderate shooting, in fact, all tanks have bonuses for locking and stable shooting, so let's not talk about gun control here, let's say Cui Wen. Many times your chariot is in an encounter when it is moving, so stop and shoot quickly, and Cui Wen will lock the circle for you. Specifically, I installed it myself and compared it. I know this is by no means a bright patent.
In your case, if there is only one option, then in the case of E 100, for most people, it is more practical to definitely control the gun than to definitely hang down. If you are an offensive player, vertical stability is also installed together, and E 100 is necessary. There are many controversies about improving the overall performance of air conditioners. Many people think it is not decisive.
Before 8.3, there were many cannons, and E 100, which was afraid of cannons, was standard for many people. But now the artillery is strictly controlled, and three guns in one game count as days (before 8.3, two sides in one game 10 guns). Many times 1 gun, TD generally reduces 100 damage, so the efficiency of lining is not as good as before.
I have 100 1000 games, 5 1% winning rate, 52% winning rate, 19800 games), and my standard is to lose ammunition, Cui Wen, and control guns.
