I wish I could get a pink-Vixen with thumbhole for my wife. She can shoot my Ibex all right, but likes the more compact LOP of the Vixen.
Anything can be built ..................... just think hydro dipping/water transfer printing and you already to go with a Pink thumbhole vixen
My dream - You go to Excalibur website and the first drop box is limb weight, then stock design (rifle/thumbhole), camo design/color, sight, string and which mailing service you prefer.
That would be a cool thing to see one day, the ultimate crossbow might be hidden in there lineup right now.
