if you can keep 90hrs a month up for as long as you can handle it, come mid November, you'll already be timed out, and imagine having a month and half vacation throughout the holiday's.

I think that it really depends on what you want, it's hard to setup schedules while sitting on reserve, and if your personal life is suffering, i'd say go for the relief line, but, if you're simply thinking about making $$, well, you know where to look.
