I have a Pinnacle standard that I use for my Spirit 100 and my other larger planes. It is a pretty strong highstart.

I stretch my rubber 2 times as long as its relaxed length. In other words for 100' of rubber, I stretch it 200'.

I have launched 2 meter ships off this highstart and they are like a rocket on it. I do not like to use it for 2 meter planes and use a Pinnacle M or Aerofoam 2m highstart, instead.
