If you dont front load, and stretch the cycle out, essentially your just making it sit in the system longer. If you front load either double your dose for the first 2 weeks OR tripple your dose for the first week only, you will bring your levels up PRONTO, and you can remain on your 8 week or 10 week cycle without ending up with a bunch of left over goods (if you had enough that is). You will also end up with a higher blood level overall if you front load.
I can email you an example if you wish, since your not plat I can't post it here. I dont think you need the Arimidex, but thats JMO. Of your two choices I would definately go for #1
