Congrats on your first Chanel bag! Your boy is beautiful!
I think my preference differs from most others. My boys and are all in goat, calf or caviar because I fear the wear of lamb on the corners and under the flap of the boy. It seems that boys in lamb have a tendency to wear more than classic flaps or other styles in lamb. I have seen and read about many lamb boys that have worn beautifully, but my experience when wearing boys is that they swing around and get banged around a bit more than my other styles. Another contributing factor for me is that I tend to wear my boys in more casual situations. I prefer minis in caviar for the same reasons. Larger bags (CF Jumbo, etc.) I prefer in lamb because it makes them lighter and they don't swing around much since I tend to wear them with the strap doubled and the bag tucked under my arm. CF in the M/L size can be either lamb or caviar for me, mostly based on color (lighter colors in caviar or calf and darker ones in lamb). Reissues I generally prefer in the classic aged calf for aesthetics and functionality.
IMO, it depends on how you will wear the bag and what it will be exposed to. Since you only plan on wearing your boy on special occasions/brunches, etc., I would think it would be fine in lamb. But if its a real concern for you, now is your chance to get it in caviar or calf since I believe both are available...and you can fulfill your lamb wish with your future CF!
Good luck deciding!
