I have a cheapo bungee (7m of 8mm OD surgical tubing plus 100m of line) which I'm going to modify. Can anyone give me any advice on:-

1. The best technique for safely joining the attachments to the ends of the tubing.
2. How much total tubing and line to use for Fletcher field.

I was going to buy 100 ft of the Dynaflite heavy duty tubing, as it appears to be the best deal I can find in terms of $/ft, although it doesn't say what dia it is or whether it is latex or silicone. It looks like the amber latex in ad pictures.

At the moment I need it for up to a 2m 800gm model, but obviously am thinking of the future too. If I buy the 100 ft of tubing, I was thinking of maybe making it up in sections so I can add/subtract to the length as required.

Any tips or advice would be great.

Thanks,
Andy
