Both the CWC's Spancalc and the AWC's calc are two very good calcs to keep bookmarked. They are among my "go to" resources for regular dimensional lumber, southern pine council also has good tables. They are generally accepted by building officials. I start slogging through mine when the timber gets out of their range. They are unacceptable to an inspector but do help during the early design phase.
