it will be easier to tiller if you even it out,, but you can tiller as is as well,,,
if you dont have a form,,you could still gently bend more reflex in the one limb or take out of the other,, lots of options,,,, I just made a bow with similar tiller issues, and just tillered it as is,, and it worked out fine,,, some of the reflex will probably bend out when it get it close to full draw,, so dont over do it,, and wait for the bow to settle in,,
