sdandrea1 Yep. Even if these are .355t, I'm going to soft step them.
If you are speaking of Wishon hybrid shafts they come in various flexes and weights so no need to soft step unless you are using a heavier stiffer flex. It's why they are great shafts for .335 Wishon heads they go hand and hand. The shaft frequency profile are on the Wishon site. What other manufacturer gives you that info.?
