I have not run MLF on cherry wine. ,, Have you taster Bing cherry wine? The acids seem off when there isn’t a good percentage of malic/ sharp flavor notes. That said to balance flavor I have back sweetened to 1.012 to balance the percentage acid. ,,, It would be interesting running two 3gallons one with and one no MLF and then doing bench trials to see what level of malic provides sharpness while decreasing the back sweeten sugar level.
If the SIL is willing to pit you should go for it. The lazy (not pitted) cherry is I nice wine and routinely gets a first place at club contest. ,,, High aromatics/ high solids is like a home made pie where you can double the fruit and not fill the pie with corn starch. ,,, What else, it is easy to bleach the red pigment in pie cherry, do not add meta to the 100% cherry off of the pitter !
