I have the following sails
Severne Motos 5.2, 6.4 and 7.8
Severne Gator 6.5
Foil Glide 2 6.0 and 7.0

I have an Enigma 160 boom which all the above fit on. However I was toying with the luxury of getting another boom, quick kit swap in variable conditions or fin to foil gear etc

I had been keeping an eye out for a 170 boom but a 180 Enigma has come up locally at a decent price.

With the Moto 7.8 and Foil Glide 7.0 being 200+ and all the other sails (bar the small 5.2) having a boom size of 184-190 the Enigma 180 would rig them all.
Maybe over-boomed but looking at the spec sheet the weight of the 180 (2.68kg) is barely heavier than the 170 (2.61kg) so the swing weight might not be much different?

Would anyone with experience of enigma booms have any comment or reason to avoid the 180 and wait for a 170?
