I you have to choose a cage like the HT v4 or any cage with a closed style. Which color do you prefer and why? I have the HT v3 small transparent that is my regular use cage. It tends to become yellowish with time and this is one of the reasons is that make me think to order a new cage but this time black (HT v4). The other reason of a black cage is not being able to see the cock when Im locked witch probably become an arousal and turn on for me with time. Thoughts?
