I have an R9 GF in .177, seems to like H&N FTT's the best so far. Bought it second hand but in like new condition, and not used much. Once I got rid of the twang/buzz (JM tune kit), it's turned into a real sweetheart, and has become my favorite shooter. I like it even better than my TX 200. You're right about the balance, it's perfect, and it points like an extension of your body. I have a Bushnell 3200 Elite 10x40 on it, reparallaxed for 35 yards. It's a great combo, and makes it a nice hunter, just point and shoot. I'd considered a .20 when I got this, but I prefer my springers be .177. Later.
