I just start playing tennis not long ago, so I don't really know much about strings. I am using the radical limited edition. Have been playing with it with the factory strung string (ultra tour 16L). It felt very good. However, it popped last week. I then went to the local store and strung the head syn gut 16L @ 59 lb (mid tension in the recommended range of 54~64 lb). It feels so stiff, much stiffer than before, and it's actually hurting my wrist. Did I string it with too much tension? I thougt syn gut was softer than poly. Anyways, I am thinking about cutting the current string and switch back to ultra tour with 17 gage. How much tension should I use? I also would like to try Head Intellistring String. Is it softer than ultra tour? How much tension do you guys suggest?
