How do you draw a high-weight English Longbow?

Most warbows are fairly stiff in the centre until right at the last few inches of a 32" draw. If the extra inch or two came from the tips as compared to the middle, would it have a different effect on the cast?

That's a good question, too. I know I tiller my warbows to only come around full compass right at full draw. I know that extra inch or two above 30" sure makes a difference in cast. As a result of this 'discovery', I'm now shooting 31" arrows. Given my stature, that's about it. I just can't get to 32".
WillS:
Perhaps with a bit of research and trial/error, it would be possible to adjust/refine a bow's tiller to give the same benefit in cast without having to be drawn a full 32". Obviously many archers just aren't built to draw 32", but most commercially available warbows are tillered the same, out to 32". I wonder if a bit of tweaking and redistributing of the working limb at full draw could make up the difference on a shorter draw? What a horribly wordy way of saying something simple.
Somebody who doesn't draw 32" won't get the full benefit of a warbow tillered to 32". So is there a way of keeping the cast the same, while allowing for a shorter draw?

No, it's simple arithmetic and physics!
Unless of course you resort to the scientific redesign of the bow as per Hickman which gave us the modern target bow, or change to a different bow style. (Arguably the Victorian tiller is more efficient but prob not so with heavier arrows like a warbow)
It's like saying can we adapt a fish to ride a bicycle... yeah, but it won't be fish anymore!
Just multiply the power stroke by half the draw weight. If the bow has a fairly linear force draw curve it's a good approximation. Just try it for a couple of different draw lengths.
Even at the same draw weight:-
Say you assume a 7" brace (measured from the back of the bow, (same as the draw length is measured) that gives a power stroke of 21" vs 25" for the 28 and 32" draws.... that's 19% increase evenat the same draw weight!
IMO
The whole concept of the handle not starting to bend until the last few inches of draw is just bonkers. The whole bow moves in unison all the time... ok it may not be visible to the naked eye, but the force is being applied to the whole limb over the whole draw. As the string angle changes the tips could possible get less leverage on them, but c'mon we are talking about longbows not horse bows with weird angles, bridges and changes in force draw curve.

I don't know Del... pics speak for themselves... First pic 3/4 draw and handle doing dick. Second pic full draw and handle bending. And that's a 30" draw. At 31" the handle does even more work.

Can I go off at a tangent momentarily, and ask you what heads are those Adam? They look huge but that could just be the camera playing tricks.
