I agree with several other replies, it sounds like the problem is how you (and others) are playing the lanes. I know just balling up or down has become the norm these days, but some conditions just require more skill than that. Instead of changing balls, or buying a ball to beat the condition, learn how to play it. You said a couple of guys that play straighter normally aren't having any issues. I would take a look at what kind of a line/gear they are playing, and try to emulate it. Remember, it's not how many boards your ball hooks, it's where your ball hooks. If the shot is only giving you 3 boards of hook, your goal should be to have that 3 board hook finish into the pocket.
I had a chance to bowl on the Badger pattern this summer, and was able to score very well. Using a stronger ball wasn't the key, in fact I found my Tropical Breeze to work best. What worked was keeping the ball very tight to the pocket, and letting what little backend I was getting finish into the pocket.
