First off, welcome to the world of traditional archery.
I would think the 45/60s would be fine if you loaded up the tip weight to say, 200 or so.(More people will come along and tell you exactly what you will need for perfect flight) Another thing to consider is you arrow weight. Heavier arrows penetrate better, quiet the bow down, and some manufacturerers require a certain GPI(grains per inch) for their warranty.
The added point weight affects the spine of the arrow(faster recovery and betterflight) and with penetration.
Im sure more will come along that are better versed than I am.
Good luck and good hunting.
