Maybe you've already chosen, but how low inductance do you need? Wirewounds are always going to have some, but usually it only gets big with higher value resistors (more turns). Getting oversized resistors could also help, as the loops inside are probably physically larger (which if they're using the same restive element, means there's fewer turns), but it's not always the case... it's probably best to get a few and choose the ones that are lowest.
As an example, I've got a few 10W (2 Dales and an Orevox) and running through the LCR meter I get:
100 ohm - 5uH @ 1kHz, 3.1uH @ 10 kHz, 3.2uH @ 100kHz
50 ohm - 3.7uH, 2uH, 2uH
1 ohm - 0.3uH, 0.3uH, 0.36uH
And a 2 ohm 5W (unknown brand)- 0.2uH, 0.14uH, 0.2uH
