ND you stated that you have just under a 70 inch wing span, that is just a tad less than me. I draw 26&1/4". When i slightly open up my stance it goes to 26" for both hands. I shoot both right and left handed. I have turned a number of compound shooters to trad archery, they generally loose a lot. Those that went from recurve to Hill style bows try not to lose much draw, but as the Hill style of shooting sinks in they average about an inch and a half shorter draw. Of course you can shoot Hill style with a recurve, there is a slight variation draw length due to the deepness of the grip. A recurve grip tends to want the wrist and bow arm to be straighter. You may have a 27+" draw with the recurve and then a 26" draw with the longbow. That slightly bent bow arm with a straighter grip bow is your friend, don't fight it. Just try to use the recurve in training without jamming up your bow arm and bow arm shoulder. Remember take it slow, no one will penalize you for sinking into your anchor for a bit. Allow the bow to cant and find that sweet spot with your middle finger where the eye is over the arrow. For myself it is on the front of my first molar on both sides, thumb knuckle on the corner point of the back of my jaw and my index finger under the orbital of my cheek bone. I have people feel around with a light bow without shooting to poke around until they find the sweet spot for the three points to settle. Personally, I would stick with a straight or slightly saddled grip, with that Misty Dawn. The slight saddle with the tapered belly flat on my duo shooter fits my hand perfect, I just let the whole thing settle right where it needs to be, with no thought my part.
Oh yes, when learning form, work on one aspect at a time until it becomes automatic.
