I xp'd my BLM to 75 from zone to I-9 area and never went after the 4 in the J-8/9 area and personally saw bluestreak pop at least 3 times in the I-9 area.
I have camped this NM twice.
The PH is lower one of the two Archaeologists at J-8 and K-8 in your widescan list.
Do bolts land reliably on this NM? i.e, blood bolts with 230 Marksmanship on THF? Obviously asking for THF solo.
