I don't like the actions on most XMG or SI casting rods myself, especially if you use braided line. They are so fast they don't cast as well and they're more prone to drive-by's. Your rig needs some elasticity. The spinning rod actions are more moderate/flexible. Some people like the real fast actions. I'm not one of them. The only extra-fast Lami I use is an EXS92M, which is my #1 salmon hardware rod. The power in that rod is amazing, but I don't like casting it. Steelhead takes are usually drive by's with it. My old Cert Pro's are superior steelhead rods IMHO. I have not fished the SI's yet.
