Help wanted with Looker1 / 2 urethral tube length beyond base ring. I am about to order a new Looker 1 and my current Chinese cage has a tube extending 5mm and this I cannot feel anymore. What is a practical length that one could accommodate without discomfort is it 10mm (looker standard) or longer say 15mm ? I know that the longer the insert past the base ring adds security but I would not want it to be at the expense of comfort and agility for long term wear as I will most likely be fitted into this cage for a month at a time because it is open and easy to keep clean. My current enclosed like a Looker 2 smells and needs cleaning every day. Has anyone experience of 10 and 15mm inserts?
