Tiller looks good to me... mind I've only made one Molle'

I asked the same Q on levers... I think thin as you dare

, just take 'em down a whisker at a time and quit at the first sign of flex (or go back a tad

)
I went for a slightly triangular section, wider on the back, slightly concave sides, narrow on the belly... I was trying for a flight bow.
What is the wood?
