Don't get too excited about seeing changes...

Seems to me there's only one major change this year.

Just noticed the change - does it make the event easier?

I don't think it really changes the difficulty of this event. It will always be a VERY difficult event to get right.

Exactly what I thought too. I think our state director is planning to make a standard setup, but that's just for states. :( I really hated the device they had at Nationals.

I don't think it would be a bad idea for NSO or at least your friendly state director to post a plan for a standard (state or nats wide) drop device just to clear things up.

(Thought I think my state dropped Bungee Drop last year cause we didn't have a room for it..)

I don't think it'd be a bad idea either. In fact, I'd say that it's almost necessary to create a standard dropping system as the rules don't make that clear. It's like testing bridges without knowing how far the bridge has to span or something. I did Bungee Drop for an invitational, regionals, states, and nationals, AND they had a different dropping mechanism every time. Which means our data was useless XD. Every time was basically a test.

Obviously it would be really nice to have a standard drop mech in the rules but since that hasn't happened the least proctors could do for all competitions (specifically for states and Nats) is post a video of how it works. I remember seeing pictures for the drop mech last season and often times it was unclear what was happening...

So, what materials have been successful in the past? Our previous year's sadly team did nearly no preparation for this event, and the wiki is dismally devoid of information. Also, would you recommend having multiple of the same cords, so that any effects of the cord stretching over the course of a year is minimized?

I think many different materials can work for this event. This event seems to be inherently inconsistent (somewhat) despite the materials. I believe this is definitely an event where trial after trial after trial is required. It wouldn't hurt to make a couple of the same bungee and then test- that should tell you if your material is going to stay consistent over time (it probably wont if you keep it all year...).

Does anyone know where to get elastic bang or metal springs that will meet the required k value, i cant seem to find a meter or more elastic material of any kind that has an appropriate k value for the event. Last I could not find anything that was a meter long so i had jerryrig 5 rubber bands tied together. Our testing was incredibley inconsistent, we need a new material and i cant seem to find anyhting on line or in the area that will work. Does anyone have any ideas.

My team is currently in the process of testing different materials. We're looking at fabric elastic, contest rubber, and latex surgical tubing. The fabric elastic you can get from local craft/fabric shops, the contest rubber from hobby shops (they're mainly used in things like balsa wood airplanes), and latex tubing from stores like Walmart. You can also get any of these online, and you can get them in fairly large sizes.
