I'm with you.... Your "Gut" is telling you this is NOT up to a good Spar Standard...
If Aircraft Spruce sent that to me... They'd be sending me replacements...
In fact... They sent me a replacement because one spar weighed 5 lbs more than the other...
To me.... Looks like good material to CUT-UP for cap strip material.....
I'd spend the $200 on new Spars....Peace of Mind.... Priceless

Wavy grain is acceptable provided the limits are not exceeded. As you have already noted, sometimes necessary to evaluate all four sides of the board. Can't tell from the pic if it's acceptable or not and even if it is acceptable, whether of not I used it would probably depend on where the defect was located in the final product. I wouldn't get to excited about wood that barely meets minimum acceptable requirements, especially if the defect falls in the most critical section of a wing spar. Yea, it's acceptable but is that really what I want?

Dave, if it was me, I wouldn't use it. Why worry about something for the time you own the airplane when a couple of hundred dollars would take that worry away. I wonder what the top & bottom of the spar looks like?
