i guess that this does not really help. i was wondering if the scroll you god is the same as the one in x3II. on it, it is a very tight wheel, that still overshots, but very very tight.
Not too sure...what does not help..was answering your question and no mention of X311.....also don't have it...so not sure what you mean...
For now...the X5 is NOT giving me grief but only JOY....sound is fantastic awesome and everything is working fine......unless you are buying X311 only for the scroll wheel
Lol
