I got the XL samples from ABS in their "Garage Sale" and they hold an edge better than any broadhead I have shot (still sharp after targets, dirt, and a wounded coyote). The XL with 1.5" blades seem like a good deer head, but I didn't want to pay $100 (on the XLs) plus shipping for 3, and plan on using VPAs again this year.
To answer your post, based on their following, as a US dealer of German Silver Flames you would get some orders, but can't say if it would be worth your while.
