I currently play a set of DCI irons in 4-PW shafted with Tri-Spec steel shafts in regular flex.Love the feel of the shafts and hit them well. As you can imagine, because of their age and usage level, these irons are fairly worn. I am looking to possibly replace them in the future. However, try as I might, I can't seem to find any specs for the Tri-Spec steel shafts. Does anyone know the specs? Also, what would be a similar shaft to try that would feel similar. Thanks
