Yes, I angle mine to where they sit just behind the knuckle. Feels better to me and is more forgiving of being loose. To echo the wise Ned, I really like John Doucet's straps, that's where I buy mine from. Comfortable straps, good prices, and good guy to deal with.
I use the hardware at the end of the strap to mark the spacing, then use leather punch to mark 3 holes in a row on each side to allow for adjustment.
