Dustin, the last three silverwood arrows I finished weighed 530 gr at a length of 29" using a 125 gr field tip.
The big advantage of these shafts is that they are exceptional well matched. If you get a package of one dozen they will all nearly weigh the same ( +/- 5 gr or so) and more important they will have nealy exactly the same spine. By the way, spine and weight is already written on each shaft and they are barrel tapered for better dynamic properties.
There may be better respectively more durable and heavier shafts for hunting but for 3D tournament or target shooting I do not know better shafts.
@Schlechdee. Thanks for the hint but I have already called them this morning and they do not have my spine weight (75#) in stock right now. They told me to call back in two or three months, so...
