I keep all three of the lovely ladies, A,V,&J slap the "Horn Dog" patch on so my PC doesn't have to worry about picking
I haven't had much of a problem with Aerie, sure she's got low HP, but she's a magic user/cleric she's not a tank. She's got no business getting in a one on one scrap with anything anyway, She's support. Stands in the background chunking Magic missles, fireballs, Holy smite, Cloud kill etc. and healing.
Armour Va-Va-Vicky (Viconia) up give her the belt of fortitude, and the mauler's Arm mace and She can scrap with anything her little Drow Heart wants to.
Ja-Hotty armour her up and give her the staff of Rhym, and sit back and watch her wade through any battles.
It's usually my PC, Minsc and 4 bady dolls
