Porkmeatballs, so much depends on shape and bohyancy versus ballast placement etc. With flat sided gliders I personally like lots of bohyancy and ballast , I like to keep ballast below centre line from tow point to tail or even lower . Sometimes this means more than 2 ballast points depending on shape and bohyancy of lure . I'm Sure if you can post pics there's guy's here with glider making experience who can help........gider
