I feel bad for starting this huge debate. For those who are having problems pulling off a reflux, I doubt that you will have more success with a push pull. Mine was successfull, but that is me. The one great advantage that I can see is time, you will know if you were successfull in hours rather than days. The push pull is more complicated, and defies all principals of organic chemistry, but it works. The decision remains with the cook. Think about the recorses at your disposal read everything you can find on the subject again and again. when you think you have the process down, read it again! Bee safe, follow Warlock's instructions, and take your time, you will have plenty. If reflux is working well for you why try to fix something that isn't broken.
But what do I know, I was never here.......
