I can actually FEEL the shift now, not some boingy, springy, bouncy jerk between shifts anymore! I decided to upgrade when my t-case started to get gummy between 2Hi and 4Hi and it would sometimes take me 20 min of shifting and doing figure 8s in the staging area to get the dang thing out of 4 and into 2. Works wonderfully now. Only one step I got confused about, you do have to trim your all-thread to your specific application which isn't in the instructions but you kinda figure it out as you're installing. Good luck!
