Will this cause any significant issues in delay or performance? Intuitively, I think the addition of a big switch on the trace will add additional inductance/capacitance, but is there a way I can better estimate the effects? 

For reference, the transition and propagation time from the gate is ~10ns. Given my circuit is fairly sensitive to delays, would I be better off using 0 ohm resistors and solder/de-solder every time I want to switch?
