I like both rods, but they're quite different from one another.
The Lami is definitely a light action (6-10 lb line rating).  It handles small jigs well, especially where I have to hold the fish in a hole (like blue creek).  Also great with 6lb leaders when I'm low water summer-running.  I don't use it for C&R because I'd rather have the backbone so I don't have to play the fish to exhaustion (which you have to do with big fish).  Also don't use it too much during high flows.  In other words, if you hook a big one, or medium sized one in fast water, you need room to walk him down.
The Loomis definitely has a medium action backbone.  I can turn the head of just about anything with the rod.  With the additional backbone and 6", I've made 100yd floats, had a takedown, and succesfully hooked and landed the fish.  It handles 8lb just fine, but thats as light as I'd go.  I make sure I keep a loose drag when I'm using jigs; don't think I've straitened a hook yet, but its possible.  The rod is physically heavier than the Lami, which is the only drawback I can see.  
There you have it.  I guess if I were to pick one for both winter and summer fishing, I'd go with the Loomis.  When drift fishing, the added weight of the Loomis is a little bothersome, but I've never had that whistling hook set.  If this isn't a problem for you, go for the Loomis.  You can't beat the Lami for summer-running though.
