Rick, I'm gonna hold off for now. After researching the DSFI on that shaft, it seems I might be good for now. I order some Powerflex FW114 shafts in .335 and .370 yesterday from Hireko. The DSFI on the .335 is 65 compared to the 79 of the Easyflex.
If these don't work out, then I'll hit you up. Thanks for the help.
