You might try the doug fir available from Braveheart Archery, he uses the surewoods. I have used a couple dozen of them now and have not had to straighten even one.
Tim at Braveheart can get heavier shafts, too, if you want extra weight. I got some heavier 60-65's and put a 160 STOS on it, ended up with a 715 grain arrow. My normal doug firs weight right at 550 all put together, so you got lots of options.
Give Tim a call or email, the surewood doug firs can't be beat for wood arrows. They're tough, easy to work with, have lots of grain so nocks are easy to align too.
