I don't think anyone is suggesting that you have to perpetually compensate for out-of-trim weighting without fixing it.
It was noted that OP's posture was not ideal and that extending hands and bending knees, which is desirable for reasons other than simply adjusting trim, might go a long way to solving the problem. Get the posture right, and then go from there. Otherwise, you are shooting at a moving target.
So, best advice is:
1. Make sure you have the proper amount of weight. If you're overweighted and forced to carry a bigger air volume in the wing, that can throw off your trim. Also, if it is, in fact, the case that your integrated pockets are positioned south of your center of buoyancy, then it's even more important not to stuff more weight in there than is needed. So, get to the minimum weight you need. That's step 1. For tons of reasons.
2. Then fix the positioning: Extend hands more and bend knees more, so that the fins are higher and closer to the body.
3. If that doesn't fix the issue, and you're still foot heavy, then try moving cylinder up a bit. This makes a big difference.
4. If that doesn't fix it, and I'd be surprised if it doesn't, then consider moving a little weight out of the integrated pockets onto a cam band trim pocket.
The point is don't paper over an issue that is probably more related to "form" than to "equipment" by moving weight around until you've first got the amount of weight correct, the posture fixed and done whatever you can with the cylinder position. Then, absolutely, use a trim weight pocket if you need to. There's no need to fight the gear.
