I have been tracking how various NC entities return from Dronelands to the north. While it seems every FC has a different preferred route, there are some marked trends that should be noted by anyone who plans to incap JBs or bomb the fuck out of them. Everyone originates from LS-JEP, and from there they make their way to Q-CAB. Depending on which area of Venal they want to go to, they can also choose to go to UMI-KK, which is on the JB route from Q-CAB. Sometimes they take JBs halfway through and burn the rest of the way, sometimes they just go all JBs. It really depends on how much a rush these guys are in, and if the JBs are fueled.
Below are two of the most common routes FCs take, the first being the fastest and most direct. The second, well

but they still do it sometimes.
* LS-JEP take 8.1 jb to Y5J
* Y5J manually fly one jump to 2CG
* 2CG manually fly one jump to QFF-
* QFF- take 7.1 jb to IMK
* IMK- take 9.12 JB to Q-CAB
* LS-JEP take 8.2 JB to JZV
* JSV manually fly to Q3-BAY
* Q3-BAY take JB 6.1 to RVCZ
* RVCZ take JB 3.3 to 0R-F2f
* 0R-F2F take 6.2 JB to ОJ3L
* OJ3L manually fly two jumps to Q-CAB
From Q-CAB thеy can trivially get to UMI-KK via JBs
If we anticipate Goons‚ or any other area from Deklein, to come, they will take a route from VFK to 4U90 as follows:
* VFK manually fly 1j to 2R-CRW
* 2R-CRW take 8.14 jb to 0p-F3k
* 0P-F3K take 11.8 JB to 4u90
Though they could also get to the UMI-KK network a myriad of different ways if they had to, though it would be more than three times the distance.
Any entities coming from Pure Blind could manually fly until they hit the UM-KK jump bridge network, though the easiest way for them would be to take the Pure Blind JB network to EC-P8R or take the JB network the other way to О-NXZ. Both of thеse systems are on either side of EW0K‚ ѕo manually fly 1j to EW0K, and thеn hop on the Goon JB network straight to 4U90.
