I like it.
I've always bought vehicles that would perform multiple functions. When my boys were young, we had a couple minivans that could be configured for travel, carpooling, shopping, camping, hunting, etc. I now have a basic 4 door pickup. Neither vehicle type turns any heads, but they did/do literally everything a vehicle can do except win races, lol.
I used to carry a Swiss Army knife. I now use a multi-tool almost daily. Neither one of those knife types get oohed and aaahed over like the beauties made and shown in the knife forum. But they perform the tasks for which they are designed very well.
Randy's new innovation will allow me to use the very same riser, with the very same grip, in every possible situation I desire - now, and into the future. I love to do pack-in hunts and prefer a 2pc for the ease. This bow covers it. I like shooting longbows and recurves. This bow covers it. As I get older and have the opportunity to travel to more shoots, I may want to drop weight a little for 3D's and maybe shoot multiple classes. This bow covers it. - All with the same exact grip in every situation. I see this multi-tool riser as being another way to help me become an overall better shooter by never needing to switch bows, just limbs, if so desired.
Bonus advantage: I see so many beautiful bows created by wonderful craftsmen, but simply don't choose to own multiple bows with different grips and feels. Now, if I want to hunt with both longbow and recurve, and drop a few pounds for both classes in 3D, I can get 4 gorgeous sets of limbs to use on the same riser and have the added convenience of a quick, simple breakdown for travel. I can experience ultimate utility in a bow AND turn some heads - unlike my minivan.
