My girlfriend really wants a compound bow for her birthday. That's coming up in a few weeks. I have a budget of about 300 bucks. What should i be looking at? She's 30 (turning 31) and is not what I would consider "strong" so I think any draw weight over 30 is going to be impossible for her. Not that I know this. So adjustable is preferred. But I am your expertise mercy as I know NOTHING about archery.
