national scores are more like 0/0 or at least 2 pins hit

Been having trouble with the design this year. We used a PVC pipe and and ram-rod thing (more like a smaller pvc pipe inside with a nice cap for the ball to sit on :D ) with eyebolts in the sides for the slingshot bands to attatch to but we've broken the eye bolts multiple times along with a rubberband once so we've had to reshoot everything quite frequently :). I wish that we hadn't just broken it a little bit ago, as i dont think we'll get EVERY single thing, but we'll get close.

How did you break the eyebolts? The solution for the bands is simple don't push it to hard, if it depends on the bands being extremely stretched out then I might suggest getting two identical bands and testing with one then putting the other in before comp. Preferrably you test and fire at comp with the same elastic but sometimes that is impossible because of the design.:|

have the event proctors at nationals, state or regionals ever placed the elevated target at 2 meters?

I heard that the people in Pennsylvania did that. You'd have to get on of them to confirm.

i bet a lot of people would overshoot that or have it come in too low

I didn't compete, so I don't know the exact length, but it was very short. Haven Chuck would know for sure.

Trajectory targets for C division PA states were

6 meters 2 meters high

8 meters on the ground

The targets for B division were not as tough (and neither can they be in terms of height)

Many did: I know for sure that Uniontown and Harriton (1st and 2nd place respectively) hit both targets. Does anyone know if Plymouth Whitemarsh or Wallenpaupak also hit both targets?
