Iphone 5S on 7.0.3 wanting to jailbreak

Unfortunately I missed out updating to 7.0.6 and I dont want 7.1, are there any reasons why I should not use the current version of evasion to jailbreak from my current 7.0.3 version. Also, I noticed that 7.1 is already downloaded but not applied to the phone, will there be any way to erase the update, (takes up a lot of space)
Finally, any pitfalls I should be aware of?
Thanks
