That early ACE/PML nose cone comparison shows why I used an ACE 4" cone for my upscales that needed a PNC-60AH profile back in the early 90's. The longer body and rounded tip was much closer to the 60AH profile. I eventually started turning my own balsa upscales, but the ACE cones served me well in my early HP/EX days.

I like that #1 paint scheme.
