Heres something to consider......at what airspeed in relation to vmc does the POH advise you to rotate?
compare C-310 to Be 55/58
I would be more likely to continue a take-off in a C-310 for example than an Apache with a failure at 100 ft......
the basics though....
-actions for failure before v1
-ditto..after (no more usable runway is a good point to continue rather than push nose over for landing...)
-weather (VFR return or DP then instrument return)
-performance (ie budget for 200fpm climb or descent at vyse)
-plan b for emergency.(ie field nearby/highway etc)
-mel's
-initial course for departure
i guess theres no hard or fast rule.....brief what is needed to stay safe...
my 2 cents..
