i would (and have, in building a scrap tele) go on every pickup manufacturer's website and get all the sound samples i could listen to...in the scrap tele, i have a gfs bucker (one of the vintage alnico 2's, i think) and a lindy fralin bridge sc. your tone chain is really hard thing to tie down....i have been messing with amplifiers this year. last year it was speakers. if you change gauges on your strings, it changes tone some....and it will change how you use your fingers.
duane allman, dicky betts, and the rest...the prescription seems to be a decent les paul, and a marshall....but then, they don't always tell all the secrets...and that might sound 'not right' to your ears. premier guitar has been doing 'rig rundowns'. that might be a source of ideas. having 'pulled the trigger' on a bunch of pickups, my advice would be listen long...and listen live, if you can...and wait to order until you know how something will sound to you.
for example...my epi les paul was on the 'i might sell it' list, until i recently hooked it up to a thd univalve with an el34 in the amp. whole nother deal.
