I guess it’s all in the use you make of the thing? I use the trem on my strat for very light “shimmer”.... any system would do and I much prefer the looks of the 6-point (yeah, I am known for being “stupid”). Never had half a tuning issue. If I used the trem intensively, I guess that a roller nut etc etc would be a must? Perhaps. As for the 2-point being better... had two strats with 2 point and never noticed any difference.
