Keep in mind that half the capship pilots out there have no choice but to use multiple Jump Holes just to get out of their guard system, out of the next system they control and probably another system or two to get into the action. The GMG| flagship, for example, is not a defensive ship but an offensive one. Both Hispanics will need to use seried after series of JH's to get into where the action is. I strongly believe that the rumour of JH's instability is just that; a rumour. GMG NPCs have been using JHs for 6 centuries, they are very about their knowledge and use of JHs in NPCs rumours. If they were so dangerous GMG woulda noted this and it would been stated by them.
