The truth is, it depends on what you're ultimately looking for. In fact, I've seen a few people start off with that weight and do fairly well by today's standards for "trad". Certainly good enough for close range hunting. If that's what you want, and you can draw and anchor with that bow, you might just be fine. Going any deeper may not matter, and certainly a lot of other things we discuss won't matter either.
If you want more than that, tighter groups at longer distances, for example, then things start changing. On trad forums, "aiming" is a frequent topic for discussion, (read - debate), when in reality, it's probably less than 10% of making consistent shots. (Think about it, with "trad" you're either at spitting distances or if you go longer, you're using an aiming system, whether you know it or not.) That leaves form, that takes practice - and that's where the lighter bows start to shine. There are just too many things you're not going to be able to learn, much less master, if the weight of the bow is a factor in your shot sequence.
