You didn't indicate if advancement or bonus (e.g. pin) points should be awarded during the round with 14 wrestlers. Assuming such points should be awarded, using the 32 wrestler with 5 match limit structure is best. No points will be awarded for the first round (of 32) byes because none of the matches are contested.
The brackets will always print the entire 32-wrestler structure. I suggest printing them in portrait mode instead of landscape mode (the default).
