Very nice song, I absolutely love the midrange bass and its melody. I actually like the lead synth's melody too but I agree that I liked the parts without that lead synth the most. I think for me it comes down to the actual lead synth's sound itself, perhaps go for a different lead synth sound that is in that same higher frequency range but is a more modern sound. Perhaps elaborate on that lead melody a bit as the song progresses. I loved the variations you did with the arrangement regarding the drums and gated effect.
I kind of agree with JamesDetached's comment on the hats, they sound great but they get lost in the mix depending on which speakers I'm using to listen to the song. On my regular iMac speakers they get really lost in the mix, on my Yamaha monitors I can hear them cut through alot better. Just something to keep in mind b/c you never know what type of speakers your listeners might be using. I do wish there were some splashy rides that would come in at some parts of the song to assist the hats and keep that great "rolling" sound momentum you have with this song but that's just personal preference. I'd keep the snare(s) you have and perhaps layer another one that is snappier to help the snare cut through especially if some rides or additional hats are added.
Overall, you have a great song on your hands bro. It has a great momentum and energy to it, it has a SOLID foundation for a great dancefloor track IMO. Actually it has alot more than just the foundation because all the elements are there, it feels like it's just one revision away. Keep it up!
