Whole sign is interesting. Others swear by it.Mine has a lot of "cusp" planets when I use the Placidus. And I am cool with how complex that can get.
I have trouble seeing Mars strictly in my 7th. When Mars in 6th is just more descriptive of my Job situation.
Also Moon in 3rd cannot be denied. But if whole sign, it is strictly in the 4th.
I had trouble with Aries rising. Thought I was more Taurus. But had it rectified. So if it works in whole sign for you, go for it.
