FX Impact MK2 Power Plenum 720 upgrade?

My Impact MK2 .25 cal w/ Power Plenum is in need of a complete reseal, rebuild, and I am considering upgrading to the new Power Plenum 720 and Power Block. Have many of you gone through this upgrade and if so what are your final thoughts? Thanks in advance.
I did it to my mk2 .22 and my gun seemed to be more consistent in it's shot cycle, also when shooting at higher power it wasn't as rough on the internals
