Andy, I would like to try both mods on my Gem, anything to make it easier (yeah yeah everyone I know its already "easy" ). Have you got a step by step guide with pictures showing how to do it already posted? If not, fancy doing one??
The Benson Twins don't really go into a lot of detail about the trickline, but it's a pretty simple mod.. take off the trick line, shorten the standoff lines and then add a new trickline using a longer bit of bridle line looped at one end (ensuring the standoff connectors are attached to it) and then pull it tight until the wingspan is 2150mm and then mark the line. Release it all and tie a loop at the mark.
