Some of my favorite straight holes from this year:
Prestwick #1, 10, 13, 17
Raleigh CC #1, 11
Rustic Canyon #2, 13
Royal Troon #11
Lost Dunes #2, 11-12
Cuscowilla #15
Pinehurst #2 - #14 (Not sure I'd totally agree with Jim Lewis #2 is straight....but ok, offset tee-box doesn't really count as a dogleg or bend....great hole none the less)
Southern Pines #16
I find the most interesting straight holes are often built on sloped land, hence the fairway width is often naturally reduced. These holes also usually have very interesting greens. And often times the architect is able to include a mound, side-of-hill, bunker or some other landform that juts into the fairway to create interest, although it really doesn't create a bending hole
