Big Block Ring Compressor - Which one?

@RustyRatRod I've wondered how well those work that was a set I had my eye on. Do they hold pretty well or are there issues like the compression sleeve type I have, where the rings sometimes pop out the bottom and hang up?
@RatBastid and @MoparMike1974 from what I read the adjustable (and non adjustable) tapered styles are best suited with a studded block (to hold the heads on), as the studs help "place" the ring compressor. It makes sense, but does anyone have experience using them on an open deck?
Always works fine for me. You have to keep tension on the pliers with your hand as you tap the piston into the bore. I always go gently because every now and then one does hang up, but I just back it out and do it again.
