[CAUT] non-Steinway hammers

[rwest1 at unl.edu]

I'm about to replace a set of original hammers on a 1915 Steinway O.   
I may have to keep the original shanks and whippens.  Given that  
scenario, what is the best replacement hammer, natural felt Abel?   
Are they light enough?  Are current Steinway hammers so heavy that  
there's no way to trim them to a weight that will work on original  
action parts?
