They should be fine but you may want to look into carbons . Personaly as I got to be a better shot way back before carbons were even out there I went through a lot of arrows from hitting them when I shot. Even a small bend one not even noticable can affect arrow flight greatly . but until that becomes a problem you should be ok. Remember generaly a heavier arrow is more stable hence more forgiving. Abow with too much poundage tends to lead to bad form. A great article is in Field and stream will give you great advice on form.
