I totally feel what you're saying. I've been spending quite a bit of time correcting issues with my bow-hand hold, posture, weight, etc. For a while, I put too much stress on my shoulder and pinched a nerve between my shoulder blade and spine. Sucked. Then I spent too much time gripping too hard and pressing with my wrist/forearm, which messed up my wrist.
Now, I've been watching and rewatching Art of the Bow, and have been focusing on looser wrist, applying arm weight, and keeping it clean. Long story made longer, I've spent the last three months paying out the behind for new/used strings to find the right match to my style, my improved technique, and my bass. Dominants were never any good for me. As far as strings being responsive to my bowing (and my bows: some lighter, some heavier, some more firm, some less), Belcantos win hands-down, and I wouldn't hesitate to recommend them to anyone, especially someone who bows the majority of the time. Myself, I'm about 70/30 bow to pizz, and play church orchestra.
Others to consider are Pirastro Flat Chromesteel, Spiro Weichs, Corelli 370M or F, and Corelli 380Ms. I don't know how familiar you are with all these, but they are all relatively "bright" strings (some more than others). Still, I dig them all.
