During drill at the local tennis club, I demoed the n-code 6.1. Having used the HPS 6.1 a couple years ago and expecting something similar, I was surprised at the change in balance on the new 6.1 and the different feel from what I remembered. The n-code 6.1 seemed almost even balanced compared to my POG Mid. After getting used to the change in balance and weight, I thought the new 6.1 played pretty well and I did enjoy the extra power on groundies. However, I couldn't get used to the feel on volleys and didn't have the opportunity to try any serves. It seems like the new 6.1 may be a little more forgiving that the HPS 6.1. Bottom line is the new 6.1 just doesn't have the feel I'm used to with the POG Mid so no changing racquets for me at this point.
