Two new gen at bow?

[P69]

Is there any advantage to keeping a 45 lb danforth clone? 
I have a 45 lb mantus at the bow and a 45 lb danforth clone and am thinking about replacing the danforth with a new gen, to have two 45 lb new gen at bow. 

Are the new generation anchors any better in the soft mud that danforths are good with?

Thanks
