I always use ALL mirrors. I do this because the "real" rear view mirror is way too small. I installed U27 and first thing I did on-line was cause a major pileup.
If you MUST have one or the other, add an option to enlarge the Real mirror.
Hmm,
U27 was installed for about 5 minutes (mirrors are very bad)
U25 was installed for about 8 minutes (would not let me downshift fast)
U22 was installed for about 2 minutes. Here the Sound was horrible, I had random black bars running across my screen (only happened in LFS) and my sound card said F**K this and I had to re-boot my system to get sound back.
U20 Installed since the day it came out and I am still running it.
I am waiting for U28 or U29 for those mirrors to be fixed. :Kick_Can_
