Outer Limits 4x4 Board

Hi guys, i have a 3ltr patrol with 35's, crawlers etc etc. i have the standard diff ratios at present but looking at changing to 4.3 or 4.6's. Not sure what will be best or the pro's / cons involved. I find i sometimes have to ride the clutch a little to get the big girl rolling. Ive just installed a new clutch and dont wanna stuff this one. What are my options and how much difference would 4.6's make. What about fuel consumption, will it guzzle juice now if i make the change due to revinf higher. Any feedback would be great. Thanks.

From memory you'll have 4.1 or 4.3 ratios now...... 4.6's out of a 2.8 GU should do it.
