Pryso,
my guess, knowing the likelyhood that Albert tried quite a few of the pretender/contender cartridges while he owned the Walker, is that Albert had a pretty good idea of what cartridges worked the best on the Walker. and in any case; the Walker does not allow for an alternate arm, so you are stuck with comparing the Walker with it's fine linear tracking arm.
so Albert would have been in as good a position as anyone to make the comparison with the cartridges he knew at that time. he had way more experience with cartridges on the Walker than the Technics.
i have a Rockport Sirius III and sitting next to it is a Dobbins Technics SP-10 Mk3 with a Reed and Talea arm. i have multiple cartridges which have been switched back and forth. i have my opinions about this and that which is as close to 'a truth' as you are likely to have.
i respect Albert's perspective.
