LP Original Fiberglass or Meinl Fibercraft?

I'm looking at replacing my LP Apsire congas.......I've been playing congas for 4 months now and started playing with my church (they have a set of LP Classics wood), but now I realize how garbage the Aspires sound compared to other congas. I was talking with my conga instructor and he was telling me that I should get a set of fiberglass congas. I did some research and I see the LP Originals are good because they are 28" high and I like to play sitting down, but then there are the Meinl Fibercraft black congas that I heard were really nice as well and they have that sparkling black texture and are 30" high. I go to New York salsa dancing and there is always this guy there with a set of Meinl Fibercrafts that sound SOOO good...and they are LOUD too! What do you think I should get? My conga instructor also told me not to put synthetic heads on them until I developed my slaps, he said synthetic heads will prevent me from learning proper technique and I should learn on the regular leather and then get Remo heads later when I have mastered those open slaps and proper technique.
Bottom line has anyone had any experience with LP Originals? or Meinl Fibercraft? Any recommendations?
