I have a Dolomite 2 piece with a Robitaille blade as well as a few easton OPS with Iginla patterns. The Robitaille has a deeper curve than the Iginla's for sure. Also it is slightly open. I also have a z-bubble with sherwood coffey blades. I'd say the Robitaille is in between the Coffey and the Iginla. I find the Robitaille to be best discribed as a 1/2" deep mid curve that is slightly open, lie 5. Hope that helps.
