I want to try some softer strings on a hybrid string job, and bought some NRG2 and X-1 for a playtest. Read in feedback that you need to string this at higher tension, and can't find how many pounds difference is sufficient. So if I usually string my Speedport Tour at 60lbs with Pro Supex Big Ace and crosses with Prince Synthetic at 60lbs, what would I string the Technifibre if I wanted to get similar power levels, 62lbs? Any help would be appreciated. Thanks.
