I've been in a similar situation and the best option is to decide which variation you prefer of the ones you've already bought and then try to find similar ones for sale. I know that's not always possible but it's well worth the extra effort and, in some situations, the extra cost if having to pay full retail.
The problem is that even if someone posts the specs of THEIR individual frame it is probably very different from the next frame you purchase.
Only on Talk Tennis can you find people who believe
that 10 feet of lead tape has no effect on a frame...
