Being able to convert back and forth from 209 to cap is a pretty cool option. The Original DISCs had a orange FPJ with a "nipple" in it you could buy. I don't need to comply with PacNW rules but something like that in a red jacket i might find useful. 209 primers are still in short supply around here but caps are no problem.
Im still hoping they will offer a UL in a 45cal with a 1-20 or faster twist. Ive already got the 50cal Ultra Light and 54cal covered but i sure would love a handier 45.
