The last time I played hybrid archer was with Langes Messer and Tatar Bow, 15/21. Now quivers' weight was increased to some tons, so this does not work anymore I think. Langes Messer is too short for only 7 Athl with this weight.
For melee, you need at least 5 PS and a +3 weapon or 6 PS, and some decent athlectics (would not want to play with less than 6). The quiver slows you down so much though, you better get 8 Athl or more to compensate this effect.
I don't think hybrid archers are playable on level 30. I would recommend you this build for level 31, if you do not mind retiring at level 32 (you get 2 LP instead of 1 but also need double exp to reach it, peasant time is shorter, but you do not get +60 exp per tick more, but only +30 in the next gen):
LEVEL 31
15/24
8 Skills to Attributes

5 PD
