Half Ironman or not?

Question to the Slowtwitch crew?
Doing my third full Ironman in March. Went 10:11 last year on the same course.
Looking to go sub ten this time around. Normally I do a local half ironman 5 weeks out from the A race on my schedule but due to work commitments this year I can’t get to that one.
Question is:
Should I slot another Half in somewhere around the same time (probably slightly earlier and I’ll have to fly interstate) or just carry on with my ironman training and not worry about the half race?
Bit more info -Just completed Western Sydney 70.3 (Dec 14) and will have a local Olympic around 4th Jan 15.
Last year at Ironman Melbourne 1:11 swim 5:08 bike and 3:42 run , 45-49M, also self coached, hence the question?

Don’t think there’s a true yes or no answer, but I think if you’re able to find a replacement race then go for it.

I would follow your heart. Do you love racing? If so, then yes, jump on the plane and race… Do you THINK you need to race the half? then yes, race it.

Training wise it is probably a toss up. But, this is a hobby, people do hobbies because they ENJOY them. Do whatever scenario you would enjoy more.

My opinion:

HIM no closer than 8 weeks out
