Default ASP or SLP underdrive pulley?

I need to purchase an underdrive pulley tomorrow and was wondering what all of you think is better, ASP or SLP??? I have a rollmaster double chain, I have heard that the new style ASP's don't need to be machined. Is that right?? Please advise!!!

Zero complaints about my ASP pulley.

SLP looks like a nice piece, I've read that it's a little heavier.

i get a slight dimming of my dash lights with the ASP pulley on my stock-idle speed A4, but it perks right back anywhere off idle and it's not really too much of a problem IMO.

As far as I know both of those pulley's will have to be machined for a double roller. If you look on sites about the double roller they metion machining of pully. I would find someone that knows for sure.
My ASP with the 15% underdrive alt works fine. If I have my A/C on Max HIGH, and the cooling fans kick on I have to keep the idle around 1200 so it will stay above 13V. Not a bid deal though.
