Absolutely true. Flew out of there just the other day. 22k aircraft (737-300). Even full power take off on 22k couldn't get us off Rwy 15 but a downrated 20k take-off with assumed thrust at 32 degrees got us off Rwy 33. Also manged to climb to FL360. Fairly full load. Purely performance related. No real advantage with Rwy 33 as SIDS all take you to the same place would save a few seconds maybe, but that lost waiting for your 33 departure.
Thanks for asking though.
Cheers.
