I generally tried to extend side-to-side branches until they reached beyond everything below them. I then immediately turned them downwards at the points that I personally thought would be most likely to work.
Yeah, I've done a lot of that, f2b is just so much better than s2s.

I imagine I could have done better if I knew how to use the seam ripper feature. I spent a lot of time moving the search over to WLS and JLS and carefully testing various potential branching locations and partial branches. This was the most personally time consuming part of the search. Other parts I could just set up and let run while I did other things.
The two seam ripper options have their own issues and their notion of splittable does not match exactly "can be continued productively". I configure them both (V1 and V2) in most fixed-board searches if only to give myself more randomish partials to skim through so you might try it.

I also imagine that the pattern DB ends would be extremely useful for back-to-front searches. Such searches are very slow and quickly run out of memory at low widths. Since there is a very large collection of width-12 2c/5 ships in the knightt-results collection, I suspect that the search would notice an existing component from there long before it could find a solution directly.
Both the current pattern DB and the new version I sketched have performance issues trying to tackle knightt-results. The current version reanalyzes files each search which is extremely slow while the newer version only analyzes files once. Once ingested the current knightt-results repo I have turns into a 73MB DB for 2c/5 b2f which takes ~6s to load per search.
That sounds better but once it hits a result it has to do a ton of analysis to figure out best solutions for it from the DB it has. As a test I loaded the knightt-results 2c/5 asymmetric width 12 as well as the original sparker you have on the west side of that main b2f branch and reran the search from that split. It loads the DB in like 6s and immediately finds a hit but then it takes it ~12m to decide what the best completion from the DB is. The best completion by population conflicts with the next branch to the east. Then is takes another ~7m before it outputs the best completion by right (east) clearance (with ties broken by population) which does not conflict and is a little smaller:

Then it goes on to the next row, has another hit, another ~12m to find the same min-pop completion, another ~7m to find the same best-right-clearance completion, etc.
I don't think I'm gonna leave this running or worry too much about trying to optimize these branches in general, this is just to demonstrate what it can do. In a context where each hit is valuable and worth waiting for (as opposed to optimizing known hits) it might be okay.
EDIT: I looked over the algo and it makes no sense. The results it produces are fine but it is insanely wasteful. I've rewritten it and now it's running in the ~1s range per hit. There is still ~30s on the first hit where it has to stop and compute best clearances for the entire DB but that's only the first hit.
It's still painful enough sorting through the flood of duplicated output (it keeps finding the same results on each row) that I'm probably not going to try for any further optimization of the wick stretcher.
