i am using megajolt for my ignition so no dizzy to worry about.
Matt, you have entered a world I know nothing about. However, the fact that you're running MegaJolt makes me wonder if your ignition map is right for your engine. If you can temporarily re-fit a standard dizzy and test drive the car, you'll quickly determine if the problem is fuel related or ignition related.
BJst416, most people limit their use of double-clutching to cars that already have damaged or no synchros. If the syncrhos are in good order there may be some reduction in their wear, however it comes at the expense of more wear on the clutch components.
