As i can see your femur is pretty short, so i would do 8 cm femur + 4 cm tibia and you will be well proportioned.
Hey Ted68,
I have much respect for you doing quad at such a decent age.
Doing only one segment is already hard enough for anyone at any age, so i can imagine it was, and likely still is a tough ride.
You for sure didn't miss the nuts to go through this.
I saw in your diary you're having issues. I hope you're doing okay man and making progress.
Also, thank you for your opinion on my proportions. It's highly appreciated.
