Silhouette:I'm also just starting to learn detailing so I'm not really sure. However, I have read good things about the bi-gloss. Not the best but it supposedly can produce a good shine. If you consider its price along with the good reviews, I'm thinking this is a winner. I'm not familiar with both La Shens so I'm not sure if they are any good.

Zildjian: Last time I visisted Southmall (About a month ago) I saw a bunch of soft99 stuff. I'm just not sure on what types are available. Maybe you could check out SM Hardware.
