Shot for shot, the XL will tend to be more accurate due to the longer ATA.

I was in the same dilema when I was torn between the Trykon and Trykon XL last year. I shot them both side by side and liked the XL better.

Granted the XL is about 4oz heavier than the standard Vectrix, however the weight of either bow is managable, certainly heavy but managable.

If I were to buy another bow this year it probably would be a Vectrix XL.
