I want the dark grey lambskin flap with new chain...but I'm so worried about the alleged delicacy of the lambskin. I have the 2005 black reissue and I've used it to death with not a trace of wear (I;m talking restaurant floors,tossing it onto the floor of my car,etc). Is lambskin much more delicate than this? How does wear show on the lambskin? And,does the dark grey come in caviar? My store only has it in lambskin. I suppose I have enough large,rough bags...Muse,roxy,paddy,bay....I could use the grey lambskin for "best", but I like to be able to carry my bags anywhere!!
