Currently throwing a beat 175g x comet and want to add a premium to the bag. Looking at a 170g old esp blend or 173-175g '19 MJ esp, what do?
So depends if you are trying to get something like the X.. It's closest cousin would be a flat esp and a few grams lighter 170 sounds good, maybe 172 max. If you are looking for a complement to it, look for more dome and lighter 170 or an ESP at similar weight like the MJ.
The dome will give you the flight you want in a couple years with a little extra stability and more glide.. once it breaks in , a flat one will be more instant satisfaction and will wear into a more understable flight faster.
