What ROMs work well with the dock?

view story

http://forum.xda-developers.com – I am anxious to try to improve the performance of my TF700 by installing a custom ROM. It just occurred to me that I should ask if using my keyboard dock will have any problems with custom ROMs. Can someone recommend Jelly Bean (4.1.x or 4.2) ROMs that won't prevent use of the dock? Also, if I start using custom ROMs, how hard is it to revert back to the stock Asus ROM? I'm assuming I just need to download off of the Asus site and flash like any other ROM? Thank you very much and your help is appreciated. (HowTos)
