You did not add a poll to the thread nor did you ask any qualifiers for what you are looking for. If you are asking for the best over all around frame, out of those stated, then I would give it to the Volkl PB10 mid. The 6.1 95 is an amazing racquet as well and is more used. The other two frames lack the stability the other two have and the LTD, while a good frame in its own regard, is too underpowered for a modern play style of tennis.
