I used it, and liked it a lot. I used a size 6 needle for the pattern that I made and it seemed to be just the right size for that yarn. A size 8 would have made too loose a fabric, I think.
You're really close on your gauge, only off by .25sts/1", but I'd keep an eye on it as you go. Even that little can make a difference. For example if you're working on 100sts:
100sts/19sts per 4" (your pattern gauge) gives you a width of about 21".
100sts/20sts per 4" (your gauge) gives you a width of about 20".
Depending on what type of fit you are going for, you might want to consider a size 6 needle. You don't want it to end up too tight.
