Thanee said:As a halfling (she's human) she would have better saves and two higher attack bonus, but would lose the bonus feat (which is worth as much as the save bonus roughly, if you use the FR subraces, you can even have the bonus feat like the human instead of the save bonuses!) and some skill points (would gain some weaker skill bonuses in exchange). The small size would be no real hindrance, as she cannot escape a grapple or trip attempt anyways, but would offer some more advantages (better hide, and AC).
If she is a halfling, she will have slower speed. That will make her a little bit harder to get into "right position for shooting". I have seen this happen many times for various small shooters. Because of cover rules, positioning is more important for shooters than for usual spell casters. In my experience, combination of slow speed and the lack of low-light/dark vision often hurts a halfling shooter (read as wasting a round to reach a viable position to shoot). Which can never be compensated by +2 bonus for shooting (or only +1, as human can have extra weapon focus/point blank shot).
Also, there are times when short halflings can't see the other side of, say, a 3-4 foot tall cover (like those on castle walls). Most buildings are built medium-sized character in mind.
And, there always be a moment when being medium or small means life and death. My play group have lost a halfling rogue in the middle of fire-top mountain. Because of a large worm which can swallow small characters but not medium characters. Being small is a hard way. Sigh.
