Well, it's most likely an issue of getting the right amount water into the soap I would guess. Some boars can be a bit moody during break in.
I'd try this: Next shave, get your Go-To soap, the one that never fails and you've had the most experience with. When I'm "dialing in" a new soap or brush, I palm load. Soak the lower 1/3 of the bristles in your boar for 3 or 5 minutes in warm water, then shake it out as much as possible. Starting with a barely damp brush, load the brush on the puck until you have a creamy proto lather. You may have to add a few drops of water to get the proto lather to develop. Then build the lather in your palm. Paint stroke motion works best as opposed to swirling. Slowly add water by quickly passing the brush tips under running water every 30 seconds or so with vigorous paint strokes on your palm and really pound the water into the lather. By the time you've done about 5 of these water additions, you should have lovely lather.
We want to "train" your boar at this point, and the vigorous paint stroking is also going to help fatigue the bristle tips and accelerate some splitting, which is going to help with the face feel and absorption of water into the bristle. Once she's broken in, you'll just load and go in whatever fashion you've become accustomed to.
I'd do a mini-Focus with the SOC. It's a truly great brush, and it's going to reward you if you spend some time with it. By the end of the Focus, the SOC will be sufficiently broken in and you'll have developed sufficient familiarity that you can proceed to normal operating conditions.
Edited to add a pic of mine. It has a couple hundred uses, but the tips are wonderfully soft, with great boar backbone.
