Owning the R11s driver, and having seen the 'forgiveness' that it delivers, I purchased the 3wd version straight away hoping it would have the same 'I hate rough' attributes.... huge disappointment. See no difference whatsoever from the original R11 3wd - other than it seems to have a mind of it's own at times.
Certainly wouldn't recommend anyone buy it if they already have the original version.
'Not worth the 900 creds' is spot on.
