The short version is 65.6 mm long while the Long version is 73.5 mm. More important is line release to end of trigger distance ... for Long it is just under 60mm while the short is 45.26 ... so ... you lose about 1.5cm of band stretch ... really not that much at all. If using a shaft that is 7.2mm or less diameter you only need about 120cm of band stretch to get a shaft going to TV with 2 x 14mm small ID bands. Now if you move to around 8mm ... that extra 1.5mm will be more useful as even at 380% with 2 x 14.5mm will not get a 160cm shaft with 135cm to TV. Go to 8.5mm and even 3 x 14.8mm bands at 380% will also not get you to TV. But really ... we are all splitting hairs. Take a look at GR's new shafts or the new Hunt shafts used by Abellan ... just changing to a shaft like that can get you a solid extra 5cm. But people are gready and we always want more ! For the bigger guns I will use the Long ... for the smaller guns using 7mm shafts I am using the short.
