I personally love EZ Flow so far.
I use the EZ Flow gel and find it harder than other gels I've used. Which, when you get someone accustomed to MMA-L&P... it's easier to convert them. When I used a more flexible gel, I had some unhappy campers.
They do have a soak-off range now, but I haven't tried it yet, although I hear it's great.
As for the L&P, I took my course last march and am loving it too. The colours are lovely.
BUT when you choose a brand: choose according to quality (which yes, Ez Flow has) AND more importantly, the availability of good Training and support. If Training and support are not local to you, it could make it difficult for you. And lastly, is the distributor not too far from you. If you needed something last minute, could you get it within 24hrs, or at most 48hrs?
