Maybe wait till you're a little bit further into your career before writing off the opinions of "weekend warriors"? Seeing as a lot of them have a lot of tours and a lot of experience, rather than 5-weeks-short-of-basics under their belts?
There are plenty of ex-regs who are now "Weekend Warriors". Furthermore I would hardly regard 3 months + as a weekend. They only have 2 days in them you know. Methinks my signature is most approriate in your case. Cnut.
