Cartridge for a Onkyo CF-1280f?

I have an Onkyo CF-1280f DD turntable that was made (my guess) in the early 80's. It is a good looking old table that I just got back from the repair shop. They fixed the auto return mechanism. I have always wanted to try the Denon DL-103 cartridge. Would this table be a good match for that cartridge? I know the max tracking force of the table is 0 to 2.0g...and the DL 103 requires 2.5g. The suitable cartridge weight for the Onkyo is 4-11 grams. I believe the 103 weighs 8.5g. Is there any way to add weight to the counterweight on the turntable? Should I look for another cartridge like the DL 110?
I'm a relative newbie..so go easy!
Thanks for your input!
