I just find it hilarious in general that people care that much, and how much they sounds like my 7th grade English teacher's reaction to the word "who".
The LS spring is way too wide to fit in the NF plunger tube. I suggest making a NF/LS. It's basically a NF with a LS plunger head, plunger tube, and spring. It gets great ranges.
So you suggest I just take the part with the spring in it and stick it in the NF?
