I have been using the Bulletproof Recoil tip (green = hard) since March 3rd of this year, I have them on 3 shafts and the consistency of the tips is one of the things I love about them, the tip I used before the Recoil tip was the Taom Fusion, I was surprised at how hard that tip was but I did like it, one of the reasons I went with the Recoil hard tip, I'm using Taom V 10 chalk and I have never had a tip hold chalk better than this tip, even soft tips, I have found that the Sandman shaping tool is the ideal tool for roughing up this tip, don't use any pressure on the tool, just dragging it across the tip while spinning the shaft at the same time leaves dust for residue and lasts for about 20 hours of actual playing time, I said I would never use a CF shaft and now I'm using a Becue full CF cue, so why not try a synthetic polymer tip?
