I prefer the smaller calls. Really dont have a reason, maybe just like the looks of them. The calls I turn are +-4-5/8" long and I guess thats somewhere in the middle. Looking thru the calls that I have accumulated over the years, I would have to say that in a general statement: Older are bigger and newer are smaller. Got a F.A. Allen brass reed-6-5/16", Charles Perdew-6",
Chick Majors-5-1/4", Rich-N-Tone Acrylic-4-3/4", Echo Timber-4-1/4", Paul Kinyon-5-1/2", David Starks 5-1/2". K.C. I have also seen this trend, if thats what it is, over the last few years, and I think they ARE smaller in general, but I dont know what the advantage would be unless as you say a savings in materials. My son is a mfrs rep and he handles RNT in several states, and the amount of calls that he moves is considerable, so Im sure there may be something to" smaller costs less." BTW who won the duck meat contest on Saturday nite?
