I had similar situation .
After buying 70-200mkii my 85Lmkii gathered dust for over a year. I sold the 85 and about a month later had a bad case of buyers remorse
But with 24-70mkii I was never tempted to sell the 35
The 35L just gets a look that the 24-70ii can't achieve.
I sold my 50/1.4 as the optics were in a lower class, but the 35L is my fave prime
I hate the slow AF on my 85L II....however, everytimes I shoot portrait, 85L II is my 1st choice. The bokeh and sharpness are amazing. I hope newer version will be faster and lighter.
I should've said Sellers remorse there but think you got my drift...!
With a baby in tow I found I was losing shots with the slow focus
On the odd occasion it worked,the results were fabulous...but I was losing too many shots
70-200ii was SO sharp and such fast focus,I loved it
