Well I just tried this for starters, I can always add gaffer or duct tape to the inner-tube as well, since should I need to remove it it will only be stuck in the tube and not the spring which will save the spring getting all mashed up and gross.
:Cyes:
Anyway, I have done this and will be on my first real bocking session today!
