FX Fx dynamic expres 700 cal .25 And talking about hammer weight

I think the original spring is good the 8mm hammer is 14 grams and the FX heavy hammer is 16 gram
Heavy Hammer

6mm Hammer maybe original

Tungsten hammer
 
I don't quite understand why FX uses hammer weight changes opposed to a valve that could be adjusted...their current valve could with a proper engineering tweak...

26.5 grams is a ton of hammer on a balanced valve that normally uses much less, the only reason something would bend in the 'valve train' is being over driven to the point of being bound lol, do they even engineer these things or do they slap stuff together and let consumers give it a go?

I don't want to use a tungsten hammer. I gave an example of hammers and their weights here. I would like to use an 8mm hammer but I can't find any in Europe. I wrote to huma air for a recommendation and they replied that I should use a Tungsten hammer but at the minimum spring setting. I was just asking if I could use their set of hammers that they sell on Maverick.
 

I found this link. I finally know how it's all meant. therefore, I am able to actually make it all at home and in different weights. 😁

I couldn't do it and I took out the hammer, measured, weighed, drew. the result is 12.1 grams
