Wanted to get yall's impressions on my first attempt at a Knight list before I put it on the table. Any thoughts would be appreciated.

Primary Knight Detachment

Knight Errant
Knight Errant
Knight Paladin

Dark Angel Allies

Librarian - Bike, Power Field Generator
Techmarine - Bike, Power Field Generator

Tactical Squad X 5 - Lascannon

Bike Squad X 3


Things I wonder about. Would it be better to drop the techmarine and only have 1 PFG using the points to get another tac squad/add bikes? Maybe drop one PFG and make the Lib lvl 2?
