Problem with hand position in squat

[freefall68]

As recommended in SS-BBT, I have tried keeping my wrists straight in line with my arms, but I cannot. May be my lower arms are longer or may be it is a flexibility issue, but my wrists get bent under the bar. So far this was not a problem since my squat weights were light. However, as I have started lifting heavier weights my wrists are getting sore under the weight. Only way I can keep my wrists straight is by taking a wider grip on the bar, which again is not recommended per the book.

My question is if I have to make a compromise and choose between a bent wrist and a wide grip, which one is preferable?

The wider grip, obviously. You can't allow mindless adherence to advice that doesn't apply to you to be an impediment to progress. Think.
