First find a glider that fits. Have you tried any on for size yet? 6’6” is a factor.
I’ve seen a few chunkies over the years that weighed 230.... on the moon.
Then, find a good reliable friendly scale that you like, put some water in the tail, more air in the tire(s), and go fly.
Remember to maintain VFR distance from clouds.
You look 210 to me.
