As you already own a 1197 ask yourself if it has served you well and met your needs. If so get 1198. If not go HDS. If you go HDS you will have both and then you will really know which way to go when you upgrade again. Glad to see people give opinions without bashing. I run Birds bc they were best bang for buck when I was in market. If Low was cheeper then I would probably have them. I think Low has better DI and I think Bird has better SI.
