I went with Leupold mediums, and later switched them out for high. It would be a tight fit with full length rail using my 40mm, but your 32mm should fit fine. My main reason for switching to high rings was that the mediums made me crane my neck a tiny bit, whereas the highs put the eyepiece at a perfect natural position that requires zero positioning adjustment when holding the gun in firing position. Since I've only tried Leupold rings on my SR-22 I can't comment on any of the other manufacturers rings, but basic (ie cheap) high Rifleman rings work perfect for me.
