No problem Nick.
You really want springs of equal tension or it will not work correctly.
All your mechanical advance should be in by 3,000-3,200 RPM. With the light weight of a Cobra, you can get even more agressive and have it all in my 2,800 RPM, but I would not advise any quicker than that if you are running more than 9.5:1 compression - too much of a chance for detonation.

Keep us posted!
