Alanesque - there are other reasons why your bow might begin to feel light as the day goes on. One is that it is 'letting down' or getting tired, especially in hot weather. The other is that, perhaps without realising it, your draw-length is gradually getting shorter. Both of these would result in you not getting the arrow so far as when you started.
There is more involved in getting a good distance than just the potential power of the bow - in fact the heavier the bow the more potential is lost pro rata. The quality of the bow and the skill/technique of the archer are both critical. I do not know what distances your rove has which you cannot reach with a 90lb bow, but as an example, I have reached 170 yards with a bow which is 32lbs at my draw-length (26") using an ordinary target arrow; whilst there are men shooting 50lb bows who have difficulty in getting 180yards for the clout. Just upping the poundage can be counter-productive unless the other considerations are dealt with. The best bow is the one in which the maximum amouint of potential is converted to kinetic. The best shot is a dynamic one which gets the most out of the bow
