I don't really have anything against X11, but the reasons I suggested Scrypt-N instead are as follows:
1. It's easier to implement (very closely related to Scrypt, so less work for the developer).
2. It's more widely supported by mining software than X11 at this point.
3. It's adjustable, so if Scrypt:2048 (the current level VertCoin and others use) isn't enough in a couple of years, it can be adapted as many times as needed to stay ahead of ASIC's.
4. The mining period for LiteBar is very short at only 5 years. Scrypt-N provides plenty of ASIC resistant properties to cover that short period of time.
5. This is debatable, but Scrypt-N is more "proven" then X11. It's been suggested by some (including the LiteCoin developers) that the X11 algorithm is more easily translated into ASIC hardware than other ASIC resistant efforts.
I know X11 is the new hotness, and I agree it would be a step up from Scrypt, but transitions like this are already challenging.
LiteBar is starting to show some growth, so it's important to not change things too drastically or too quickly.
The good news is that we're several months away from Scrypt ASIC hardware still, and most of it will be pointed at LiteCoin at first. So there's some time to deal with any potential threat.
I agree.
At this moment is better Scrypt-N than X11
