Oh well! :)
I did get some positive feedback on the LMF feed line from some other sources...I chose to go with the "Showtime" line because it seems more complete (and no corn, ew)..."Primetime" was more for senior horses that have trouble chewing, and WIlly is in tip top shape, and not too old yet
I'll give this another shot, and ask something else... :) So, in switching the feed, I'm told I can start Willy straight on the new stuff, just in small rations, and slowly increase over 10 days. He gets a soaked beet pulp mixture now, and I feel like slowly increasing the new stuff, and slowly decreasing the soaked beet pulp will be pointless...
Any advice on switching?
