You should look at some of the old showjumping legends like Pat Smythe, Harvey Smith and the like back in the 50 and 60s; standing martingales were used many times then but they were fitted that they never interfered with a horse jumping.
Lots of snaffles and drop nosebands too (with cavessons for SM's, thought I'd add that in case it wasn't obvious - which it is) and double bridles, pelhams and kimblewicks.
I often wonder if back then horses were better trained, they were better riders, they just used what was available, or, if horses have become progressively more complicated to ride through the years.
