I can use bows and have to say, he could probably use a big heavy bow, something that needs power to draw, but if he was using daggers, I assume he was also using shortbows, that could be an adjustment to work with his current build.
The only thing that I see that could be a detriment to him now, even with a heavy bow, would be his huge milkers, the would be on the way of the string all the time, wich would be a liability, some woman do use extra protection on their chest while using a bow for that reason.
