I really like your bow. You've done some things with this bow that I've yet to experience.
Some of the more experienced guys can offer up a better opinion, but my thoughts are that it probally can handle it. But normally you try to match the tiller with limb design. With a paraell limb the tiller should be more elliptical with the bend spread more into the middle 3rd of the limb. Leaving the tips a little stiff is matter of preference, to each their own. But this should improve cast and equal out the stress on the limbs which will keep shooting longer over time. Greg
