its personal. My draw with trad bows is a little under 27.5" and I will not go below 60" anymore. I have had a 52", 56", 58", 60", 62", 64", 66"
My hunter bow longbow is 58" and is a really nice shooter though. but i had short limbs for my titan ILF riser and that was a 58" set up and it didnt like it compared to my long limbs or my 60" kodiak. Just wasnt as accurate with it. Shortest bow I had was a two tracks ambush, which honestly wasnt to bad, never really got to see its full potential since the grip was really bad for me and the arrow rested on my hand. So for wha tit was I shot ok with that set up and probably would have liked it alot if the grip was made for me.
