That is interesting that you guys don't like the way it smells. I'm neutral about it, but I've never found it offensive. I understand what you mean though because I cannot stand the smell of sweet feed! Bleck!
None of my horses, young or old did well on Safe Choice and at $22/bag I quit trying. I switched to Omolene 400 which is touted as a 'complete feed' and Ultium and they're doing very well. I'd prefer to feed just hay, but not one of my horses will hold weight on OK grass hay and alfalfa is not available for horses here.
I'm a fan of Safechoice as well. I've tried a handful of different kinds of feed for my "hard keeper" mare, and she has done the best on the Safechoice. It put weight on my thin hackney gelding in a nice, slow, steady, muscle building kind of way, which I also really liked. I like it also as a fairly neutral option for new horses I suspect have been on sweet feed prior.
Dreamcatcher, $22 a bag? Wow, glad I don't live where you are. I pay about $12.50 a 50 lb bag, and sometimes less on sale.
The $22/bag was when I lived in Tucson, AZ and only 1 feed store carried it. When my horses started looking pitiful I figured I could spend the $22 better and switched to Purina. At the time the 400 was only $8/bag, just went up to $13/bag. The 400 is a PIA in the winter, bricks like nothing I've ever seen but the horses love it and look great on it.
