They are smother all the way from top to bottom. It feels softer vs the stock "plastic look a like" bladder. Id say this one of the best modification for this car besides the "thread mod" with CA on upper arms /front/rear.
What i mean is, the soft cilconeplastic bladder from duratrax will move with the piston up all the way, and will not affect the "pressure" sort of. The best thing since there is almost zero cost for this is to test it and feel the difference, i did, and my other M18T Pro driver feels it to.
