id start in the fortys personally, which would be around a 50#@28" bow if you draw a true 25" on your compound, but generally you draw less with the trad bow at least in my experiences. ive owned bows from 30#-60# and my favorite weight is 47-48# and i too shot a 70lb compound. everyones built different and have a different preference as far as details, i just thought id throw up my thoughts and maybe theyll be useful in your decision
good luck
