I have only ever had flexible ducting for all my small coils and a truck
inner tube for the larger one.  They have allowed me to use large double
toroids without much cost and all bounce exceedingly well.  I am just about
to receive my very first spun aluminium toroid. I believe these bounce
exceedingly badly.
