Balancing Friends & Family Money with Seasoned Investor Capital

Following on an earlier post about friends and family funding, I’m seeking advice on the ideal balance between friends & family contributions and with that of seasoned search investors in a traditional search fund. I have close connections who are eager to contribute, particularly during the search phase, but I’m concerned they may not be able to commit the same level of capital that seasoned investors or funds might provide during the acquisition phase.

I’ve received conflicting advice on this and would appreciate insights on how to strike the right balance. What mix have others found effective, and how did it impact your search fund's success?
