Doug,
Why would you recommend any shorty barlow over a full length barlow, unless it was a mechanical necessity to have a short barlow.
Notwithstanding the top grade shortys like the Celestron Ultima and the Orion Shorty Plus are good barlows and a quantum leap ahead of the cheap stuff, they cannot quite equal a full size barlow optically. This is pure physics due to the shorter focal length of the barlow.
Cheers,
