Sage is a great company that makes a great product. I'd recommend you try out some rods, the line you use with the rod can make a huge difference in the performance. If you already have an 8wt, I'd go for the 10wt. My buddy has one of the higher end Scotts that feels light in the hand even though it's rated for a 10 wt line.
In my opinion the 2-hander is not a good tool when fishing out of a boat, think of it like bringing your 12' surf rod on the boat.
