Best FW Knight For a SoB/BA Drop pod army?

Im making a SoB (Adepta Sororitas) Army mostly Drop Pods. To take advantage of SoB Amazing Heavy Flamers + Rending and Ignore Cover Melta Guns.

BA list is 3 Tacs with Drop Pods + Grav and 6 FA Drop Pods with a Storm Raven.

I have Enough points (@2k) to pick a FW Knight...

I dont know what the rules are for them atm (Im ordering the Book W/ the Knight) so I need to know the best Knight to order that goes with This style army.

PS: Sorry about grammar, its hard for me.

If youre looking to keep the theme going then Id go for the Knight Acheron. Hard to beat a hellstorm str 7 ap 3 ord 1 template

I play Sisters regularly and use the Thermal Cannon to take down high AV targets at range.

go with the Knight Acheron, run it as a Freeblade and call him Trogdore the Burninator
