I returned to recurves after shooting compounds for 34 years. I was shooting 60 pounds at my 26" draw. I went to 46-43 pounds at 26" for recurves. Worked out fine.
If you were anchoring the string at the corner of your mouth and intend to do the same with your recurve you draw length should be the same. However, other things could cause a difference. Some people over draw a bit with a compound and/or use a long D-loop or release aid combination that could make the compound draw length different.
I agree with advice to shoot for 45# @ 28" draw. If you are off +- an inch with the draw you'll be shooting 48 or 42#s, your quarry won't know the difference.
Good luck.
Oh, I still shoot both types of bows. No need to give up one for the other for me.
