DIY ratios plz
edit: do your own ratios is the message. example: that shows me at around 10" 10:1. cut that down to 7" for 7:1 ratios and remove 2" for melting and I get 5" from that. simple math
12" 10:1 for DC on the NAM 12k (take this total with a grain of salt and move on with the day)
is the 3k NAM (or frankly any NAM for that matter) still out of its range for thermals despite its exceptional skill in that area?
