Lancer Feats?

[Zombulian]

Hey guys, so I've been working with a charger that I'm not all too familiar with, the Lancer. Usually to get them max deeps I go for Leap Attack and Shocktrooper + Headlong Rush + Rhino's Rush + Valorous weapon enhancement etc. But are there any specific feats I should get on a Lancer besides Spirited Charge and the other various multipliers?

Tl;Dr Give me some mounted combat feats
