My CG/max PAX
200 max in my -4 ,and as others have said, I don't like heavy backseater with less than half fuel. The difference between a 115 and 200 lb will feel significant. Be aware, your pitch control will be extremely sensitive and it may challenge your landing/flare. I'm used to it now, and its no "bad" issue, just something to be prepared for. I have backseater 99% of my flights, so flying solo almost feels odd.
