OK to switch from Test C to Test Prop?

Yes, wait until you’re due for your test c injection then start with appropriate test prop injections.

3/8 of a cc every day or 6/8 of a cc every other day should be appropriate.

dont worry about the actual total amount per week being lower. Cyp is a heavier ester and there is less actual test in it.
But like you said, if all you care about is water retention, there is no reason to switch (unless you just like sticking yourself with needles)
