Fluctuation theories apart, I highly encourage you to use a longer ester. Firstly, Test P gives terrible pip to some people. Your dose isn't high, so you might avoid this, but there is a non zero chance of significant pip. Higher than with other esters, for sure.
And because timing the bloods while on P is harder than on a longer ester, your test levels will vary a lot depending on when your bloods are drawn and how long after your last injection.
It's better to take a more stable ester in order to have a good record of how you aromatise at a given level of test. This will be useful in future cycles.
Other minor thing is higher fluctuation also results in more acne, in my experience.
