Talk about being in a funk.  Ever since Nationals last year my spare shooting has been terrible.  At Nationals, I missed a 7 pin and an 8 pin (right-handed bowler) that cost be some brackets.  This year I am so hit or miss on spares it's not funny.  Before Nationals I estimate I picked up 90-95% of my spares, this year I'm 50% at best.  The problem is mainly single pins on either side of the deck.  After Nationals I swore I would throw straight at single pins, but I get to the foul line and I can't decide to hook at the pin or throw it straight, and I usually miss.  My friend says I'm aiming the ball and should just let the ball work.  I built my average over the past five years on my ability to pick up spares, but this year it's costing me.  I should be in the 210+ area, but I'm only at 196 and 198.  I get so mad too that it frustrates me for the rest of the series, and I hate the fact that I drop a few choice words here and there.  

Anyone have any thoughts, or suggestions for a book to read that may help?  Thanks.
