I wasn't able to try the TPT shaft, but I think it was a little cost prohibitive for me anyways. When trying out the different models at PGA Superstore, there was a noticeable difference between the stock shaft and the ACCRA. I ordered my DF3 with the ACCRA. I assume that it would have even better feel than the ACCRA, not sure how you quantify $300 worth of feel though. I'm happy I didn't try TPT or I may have been less happy with what I purchased.
