Wedge or mon mothma

My primary fleet is under thrawn right now and has bossk and vader along with a bunch of other random but those 2 and vader r the main ones with tfp... and I would go Kyle but didn't wanna put the 1 shard per drops down... it's either go for mm or just put wedge as lead (which I'm leaning towards or go for slkr and scap the rebels... I still need 9 guys up to par for slkr tho but right now I run drevan in arena (like it matters) so other than slkr nobody will take over the top slot... but the rebels would give 2 good defensive squads... right now I run a 6* malak with drevan btw but they can clean out anyone that isn't a gl... or maybe cls if they r high enough... my fleets r all over tho so could Def use some attention... right now I run geos with my ackbar fleet and a sub par hux at 4* my kru is 4 tho as well as baby kylo being 12... like I said I really need to work on my fleets... sorry bout the lengthy post and thanks for all the advice
