RE: Vectrix or Vectrix XL
I agree with what mobowhuntr onwhat he is saying.
I was told the XL was better for my DL. However, I shoot a 33.25 ATA Allegiance with no problems at all. Though, I wouldn't go shorter than the 33" of the Vextrix. I didn't shoot the Tribute because it is even smaller than that.
The longer bows are more forgiving and balance a little better.
