Replying to Questions about Rossignol SAS FS 1 Ski Boots

I am looking at getting the Rossi SAS FS 1 boots. I was wondering if anybody has used these and could give me some input on them. I found them for pretty cheap online and can't try them on first. I have Rossi boots right now so I figure the foot will feel about the same. I don't know much about the 3 piece shell and how it feels, so I'm interested about that. Also I was wondering what the calf width is like, because I have big calfs. I would appreciate any input at all. Thanks!
