Ironically, I'm finding the opposite (keep in mind this is the 16lb SSSE with lower diff). Not knowing how strong the SSSE cover is, I played it safe by going a 1/2" further pin to PAP distance. My Horizon Pearl is 4.5 and the SSSE 5". Worked out perfectly. The Horizon is much stronger in the midlane and is about 3 boards stronger overall. They've been complimenting well since I drilled up the SSSE. Horizon early when there's more oil overall and downlane. Switch off the SSSE when I need more length and more downlane reaction.
I really love the roll of the SSSE. It flares a lot for being only a .040 diff. The cover is also not squirty which I like.
