Hi and welcome to the Paramotor club
I can't comment on the Paramotors you have mentioned as I have never flown them. I would suggest that Carbon is a bad idea for spars 'or any part of the cage' so if the enduro means it's stronger and less likely to break, I would opt for that.
As for the engines, again for me, the Moster + over the 190 based on the many hundreds of engines we see in the field. It just seems to work where as the 190 seems to need tweaking quite frequently (great if your the kind of person that like to get your spanners out)
Again, welcome to the PMC.
