I'm starting to think more and more about application loading performance and RSL. Still don't quite have my head wrapped around it.
I would like to make a completely new look and feel for a flex app. Is it wise to create all new skins (assuming I have no issue with how many there are), or is it more wise to just try to hack together something using CSS?
I'm asking because, are the spark skins included in the signed swz RSL? If they are, then it seems like there'd be a decent performance gain to just try to modify your skins vs. creating our own.
The Spark Skins will be included in the RSL,but the minute you make changes to them you won't get the benefit of the RSL (unless you're just mucking with colors via styles).
