Chris, we've used the poly cord for many year but are using the belting for the first time. Is the % of reduction still the same, about 6-8%? By reduction, I mean the amount that you cut off to ensure an elastic fit.

No, you want to start with a lot less. I don't have an exact number, but I would guess 2-3%. The belting is much less stretchy and stays much tighter in place.

You can always cut more off later, but putting an extension onto an existing belt isn't as fun / clean. You can even weld these belts in place if you have some clamps and apply plenty of extra tension to the opposite side.

Re: Poly Tube V.S. Surgical Tubing

Thanks for the input. What kind/brand of tubing would you recommend and where would I find it?
