Tall fat bloke here too...
-We aren't heightest now are we?
I think i can feel a movement starting, no wait, that's just me getting up.
But back to the gi thing, i find that as a tall, fat guy the uwagi scale up in size quite nicely. It's a shame it doesn't work out for the tall skinny peeps or shorter fatter peeps either.
... solution!
Harmonise with nature.... naked aikido. Awwwww yeah.
