I bought a HiBORE today. I traded in my Ping G2 for it. I went with a 10.5 loft. I had a 8.5 loft with the G2 and wanted to try more loft. I went with the Proforce shaft. I had choice of the same shaft as I had with my G2 (Grafalloy), the same shaft I had the season before with my 983K (Aldila Green NV), or the Proforce...easy choice...it's a new toy and I wanted something different, plus the Proforce looked the coolest hehe. The Proforce is a medium launch shaft which should work well with the HiBORE 10.5.
