Hard, hard, hard string on the arm and you feel accumulating wear on the arm over several weeks of hitting.
Borne out by subjective testing and the TW/RSI stiffness numbers, which are in the stratosphere.
Alu is ALOT nicer even though it doesn't last very long. Much prefer Alu's crispness as well over 4G's dull feel.
A very interesting string. I never felt that the string was playing that stiff. Very muted and with low power output. When playtesting it, I was getting outstanding control but no free power at all. I was playtesting it in a hybrid set-up with a soft syn gut cross at pretty much my normal tension. String played very dull and I was having very little impact on the other side of the net. I am sure a very hard swinging younger player would love this string, but I am not able to take advantage of what this string has to offer. I just hit a few balls with a frame that had the playtest strings installed. Tension is still holding up much better than any poly I have ever used. Just not a good match for my wallet or game.
