  Bo, you won't be able to use teflon (poly TEtraFLuoroethylene) for 
your tubing. It is way to rigid. It's durometer hardness is usually 
around 70. You're going to need tubing that's Shore A 55 or less. I'm 
still looking for a good material myself or I would recommend one for 
you. I'm testing some new materials soon and if I find a good one 
I'll let you know.
