How would you guys that have used both coils compare the two? Strong points for each, not looking for bashing comments. The reason for my asking is i just got the D2 with a new V3i but i like the SEF, i don't want to just throw the D2 in the corner and forget about it. So i figure the quickest way to find out about the D2 compared to the SEF is to ask you guys that know the two. Just looking for general info.
