Stick it out with the guard. You will have a better chance with the majors of your choice and get to do some things you would have never done without the military. The wave will still be going strong in 4-5 years.
These 26 yo all civilian guys getting hired at the majors are very rare. There are thousands of regional captains that still can't get a call. Mil is still the best shortcut to many years in the regionals IMO.
