I totally understand- mine are at home, so I only have to not annoy myself. But you should be fine with any hood that comes with clips (of mine, only the Rambo does not).
I did notice, I just got a schneiders blanket & it has 4 attachment rings (2 per side), while my smartpak blankets have 3 (1 per side & 1 on withers). This hasn’t been a problem for me bc the hood I use with the schneiders blanket is the one I made more flexible straps for. My smartpak hood (3 clips) would need an add on strap to work with the schneiders blanket - the side clips would be fine, but the withers clip wouldn’t reach without help. I hope this makes sense. So you might just double check the number of clips on a schneiders hood if you looked at those. Both the Dover/riders intl hoods I have have 3 clips, like smartpak.
