IMO, Sore No More is the best brand. I never saw any results with Ice Tight. I seldom use; usually after a hard workout which for me is few and far between nowadays.
Sore No More was always the best selling poultice for us and the most favorite brand. But, when they were changing hands and it was always on backorder I had to bring in another poultice for my barrel racers and I brought in EZ Willow poultice by Finish Line and it has the Arnica (the best ingredient in SNM) in it, goes on good, washes off easy and you can pick it off just like SNM if you don't have water right there. It's been a hit and great option.
