I have them both in 5 wts...I like them both...which one I fish sort of depends on my mood...one's a little faster one slower as I'm sure you know...I like the SLT on those "mellow" days Folks are going to tell you it depends on your casting style...personally I enjoy adjusting to the rod

I'm wondering why you aren't considering the ZXL??????????....that's one I'd like to cast.....
