You can not go wrong with G Loomis. I have never fished the SJR 700. However, I have three G-Loomis IMX SR 781's. Great for fishing the 1/32nd and 1/16th oz jigs from a boat. However, if I were fishing mostly from the bank, I think I might go for a longer one piece Rod.
There are times when I need to fish six feet underneath the bobber and the longer rods are best for that. You may also wish to look into the Pheonix Trout Rods. Pheonix makes one piece rods which are much longer than the rod I use.
