welcome to trad gang and trad land!
all stick bows are unique, even within the same manufacturer's model numbers. you would best be served trying before buying, otherwise be prepared to accept the unfortunate consequences that *may* befall you.
get as much time in behind lotsa different bowstrings as possible. clubs and shoots are a great way to try out bows and hopefully to get pro advice on matters such as draw length. it's not at all uncommon for a trad archer's draw length to change as one's form "settles in" correctly.
it is also quite common for the bow itself to influence draw length - longer bows/lighter holding weights allow yer form to stretch out and use back muscles ... moving to shorter bows/higher holding weights can contract your form and your draw length.
above all, don't overbow yerself, and whenever in the slightest doubt, go longer in bow length.
enjoy the journey ... most of us are still on it.
