XC Sten length?

Individual bike fit aside, is there a common length of stem for a dual sus XC bike? For stability reasons.
I have a 110mm stem at the moment, am I too far forward which is producing instability?
Any feedback would be appreciated!

Typo in title!

A lot down to personal choice in some cases..!

Though I run a 90MM on my XC full suss..

Ok thanks.
I ride medium Anthem X and about 5' 11".
How about you?

90-100mm would be normal on an XC bike!

Yea, don't go any less than a 90mm on an Anthem!!

You're right on the limit of a Medium Anthem at 5'11' so a 100/110mm stem is probably about right!

Thanks for the comments lads!
