It does not matter about W&B with the 150. They are unique aircraft not subject to such detail.
Even the flying clubs train in them overweight
Do a W&B calc and you wont carry much in people or fuel
This is the bit that does get bandied around (not having a pop at you Pace, I've just heard this a lot). I have in front of me the weight schedule for our 152.
Aircraft basic weight 1080.3 lbs
Full tanks fuel weight 152 lbs
MTOW 1670 lb
Which leaves 437.7 lbs cockpit/baggage payload. Enough for two 200 lb guys and a couple of overnight bags. Seems pretty reasonable to me.
