I would suggest we go for a fusion -pulse type drive, which would be smoother; rather than dump h-bombs out the back and expect the shock absorbers to smooth the ride out, we should be looking at fusing tiny pellets of deuterium/He3 by laser almost continually, the pulses would be so short you could hardly feel them.
The pulsed fusion rocket is at the bottom of this page;
