The NCR18650B and the 18650A are not considered high drain, rather high capacity (mAh). They are also rated for 6.8A continuous discharge, not 10A, with 12A given as the burst rating. Orbtronics
has them here with data on them.
My understanding is that they are safe in that they will not burn easily when abused. However I don't like to get to the amp limit so the lowest resistance I would use on them is 0.8 - 0.9 ohms in a mech mod. I have the feeling they would have higher voltage drop at those resistances than the 18650PF. I would not use them in a VV or VW mod as the standard for them is 10A
batteries.
Since the 18650PF is 2900 mAh, I would use them instead. You might well find lower voltage drop makes up for most of the difference in mAh between these two.
