We have switched from polycarb to polypro on the feathers, mainly due to the fact we get it cheap! The main reason weve switched is due it no cracking.

You can also heat it so that you are able to bend it, also you can actually weld it by melting it together! Were currently looking at making some bits for the top of Merlin, to put on top of the Ti to give abit more protection from axes.

If you look on the RS website i think it gives most of the data on there.

Weve had no probs cutting it with a jigsaw, what weve found was best was to use the most course blade you have (we use one for rough cutting wood) and set your pendulum motion to full (if your jigsaw has pendulum motion), and goes through like butter!
