I 'm loving the MOD, all 3 are super smooth, crisp, very light and really nice, the 3wt is probably the sweetest of the 3 but something I would only use occasionally for small flies and light tippets, for that, it will be a fantastic fishing tool. The 4wt is a beautiful dryfly rod but is very similar to the 5wt , maybe a touch smoother but so similar its hard to justify keeping both, the 5wt has a bit more umph which is handy when the wind blows and a bit more backbone for some of the trophies, so the sacrifice in smoothness is probably worth it for me. Overall there is very little in it between them, but I would say as fishing rods go they are the best I have tried so far.
Very expensive from Sage though, there are plenty good rods available that are worth the money, I don't think these would be worth the premium if you paid full retail. If you build one from a blank it works out a lot better value for money and then it would be something I would fully recommend
