Subscribing btw.
The 35/65 has been shown not to reduce front wheel spin. That would be one of the main attributes, for me, of wanting or running one. In addtion to not reducing front wheel spin, lap times dropped by going back to the factory center diff. That and cost are my main reasons for not pursuing it. These results/testing are not mine but someone I trust greatly. They also come from road racing tests. I believe the results would not improve due to auto-x's even quicker transitions. If you couple that with the fact that if you didn't have the correct dyno to tune you with a 35/65 (We do have a mustang locally that would work) it may make the decision easier. Not saying your car needs tuned for a 35/65 but it's something to think about.

The clutch style rear is just a compromise. I do not want decel lock-up that may induce corner entry push. Looking at the others that's what I opted for. I'm not sure it's the best decision but like I said compromise. I like the fact that you can add/reduce clutch plates and go either way you'd like. Once I'm able to do some solid testing I may just do that.
