Yes if I could afford SS blankets I would probably try one. I don't have personal experience with them so I didn't mention originally. Unfortunately even used they are so ungodly expensive.
SCHNEIDER'S? Expensive? I'm thinking you are thinking of another brand. I've bought the Royal Riders, Amigos and Rambos and while they are very nice blankets, when I discovered I could buy a really nice blanket from Schneiders for around $150 or less if I wanted 1200D, I quit buying from anywhere else.
I recently looked for a junior sized blanket for some yearlings and found several, and none could beat the quality or the price from Schneiders. I paid around $55 each for 3 1200D mid-weight blankets. The heavyweight is around $60 (I hate 59.99 etc).
The 1200D, Storm Shield blankets for adult horses start at under $100. If the OP is not buying her horse until March and can wait to buy blankets, they'll be on sale for considerably less.
Royal Riders, I paid $300 a piece for those in 1990? I still have 2 of the 3 I bought, but OUCH.
Amigos, I found a mid-weight at Dover Saddlery for $160, 1200D and doesn't have the same features the Schneiders blankets do.
Rambo, start over $200.
I can't justify spending that amount on my horses, I just have too many. If I only had 1 or 2, maybe. I've been so satisfied with Schneider's though, I doubt I'd buy one of those more expensive brands just because I could.
