you could try the offbeat reverbed kick thing as well. send your kick to reverb and then play with the predelay setting until the reverbed kick falls into the space between the real kix.

or play with reversed kicks inbetween. in addition to that you could play around with sidechaining.

after all, i think its the kickdrum to (sub)bass relationship that counts, they need to work together!

regarding that 'amateurish' statement from eyes without a face,
808 kicks are just about sinewaves actually. i think the result is the only thing that counts after all. but off course you can use the subs loads of synths provide, it's all up to personal taste, imho. and i like to try loads of stuff really in order to see what works for me.
