 I'm using LS-1 coils and have my pair of leading coils running off one fuse and the trailing coils running off another.  What value of fuses are working for the rest of you?  I blew 5A's on both pairs today.

I have mine all tied together, and there is no fuse.  I'm not necessarily recommending that, btw.   
 
Remember, fuses don't protect the device, they protect the wire.  The maximum fuse size will be determined by the wire size you're using to feed the coils.  It's natural to try to size fuses so that they're just large enough for the current that you expect, but you should resist this urge to avoid nuisance trips, particularly when powering something as important as ignition coils.
