I am going trough the process of choosing pads for my Chu and I'd kinda like to install roopads, but I was wondering if Conn res-o-pads would be a more suitable choice, or are roos and resopads both equally suitable for a Conn Chu?
thanks,

I've used both in Conn 'Chu's. Reso-pads can be devilishly difficult to fit and install. But once set up properly they work well. With reso-pads the installed pad height is very low; it's just barely thicker than the edge of the keycup. If the pads you are replacing were not reso-pads then it is likely that they were thicker and the key cups were bent to accomodate the seating of the thicker pads. If you then try to fit reso-pads, most of the keys will need to be bent so that the thinner profile will seat properly. They are a press fit into the cup and so heights can't be shimmed. The opposite situation is possibly true if changing from reso-pads to roo-pads or other thicker pads of conventional construction.
One issue that is of importance to the pad selection for a Conn Chu is that the key cups are typically not much larger in diameter than the toneholes. The edge of the tonehole comes very close to the edge of the pad. So the key cups need to be centered very well to make sure the tonehole is covered. When using conventional pads, the edge of the pad may have a very rounded profile and this could cause a problem with covering the tonehole if the rounded portion is where the pad is seating.
But these are fitment issues, which factor in to the cost and skill required by the technician. From a functional perspective, the two types of pad offer different benefits. The roo pad offers the benefits characteristic of the roo skin leather (which I will not go into, as it's been discussed at length elsewhere). The reso-pads offer the benefit of the taut, flat surface.
