My experience is that the folks (cult) who loved the G, don't like the G2. That always happens... Sage SP folks weren't big SLT fans at first either, they got over it. The SPL an LL followers are still at a total loss The flip side is that folks like me who always found the G to be a little sloppy/weak in recovery and tip heavy, experience deep lust for the G2. It's a little lighter, a tad quicker, and the recovery is what you would expect from a modern graphite rod. Don't get me wrong... both great rods, but I get pretty darned picky about the little stuff when the rods cost that much (and I have to pay retail for them). the 774/4 has been on my short list for a year now... just have to find the right deal. The 773/4 has become the favorite of several light liners I know.
Another rod to consider, just to muddy the pool a bit, is the Sage ZXL. I have a 8'6" 4wt BIIx and a 480-4 ZXL... and I go through awful fits of indecision when having to choose between the two... but if I were looking for something similar to the G2, the ZXL would be what I picked up. It's a bit more traditional progressive taper, and wicked smooth with plenty or reserve power. I don't know what wt your considering, but IMO the 8' and 8'6" 4wts are the sweet spot of the taper. If you are looking at lighter weights, I would cast the ZXL and the TXL.
I have about a dozen fly rods, and the G2 is the one I prefer for trout fishing, which for me is mostly on top, small to medium size streams. I have never fished a G. I have an 8'8" 5 weight that can do it all, but would love to have a 3 or 4 weight. I was lucky and picked up a new one at a local dealer who was discontinuing his Scott line for about $500. In my parking lot testing, the Sage ZXL was the closest competition, but I liked the funky semi-finished look of the graphite, the close-in accuracy and the price.
I just bought a Scott G, 8ft 4wt off of ebay and received it in the mail today. It's a beautiful rod, used very little but, now get this, the top tip section, that is the rod between the tip guide and the first guide is wavy. That's right. It has several small bends in it. I'm not sure how the best way to describe it but if you took a long nail and tried to straighten it several times you'd have a pretty good idea of how it looks. No, it has not been repaired. There is no break in the rod and no sign of a repair. Is this something that is normal or common on graphite rods? Has any one ever seen anything like this? I'm stumped. I really like the rod, it's in almost new condition but a tip that looks like a snake(well, it not that bad but you can see it if you look at it.)
