No sinew,
I did a little heat to gently flip the tips a smidge. It was naturally reflexed about an inch and took about 3.5 of set which I expected more than that really. Part of that set was losing the reflex. still shoots pretty good though and it's a blast to shoot. I didn't know how I would do shooting short draw but the shot pics are at about 15 yds so I'd say I'm good to go.
