I just put a set of Dominants on after reading many positive reviews here. They have only been on for a day so I don't really feel qualified to give a full review other than to say the feel and sound great compared to the 2+ year old set of spiros orchs they replaced. A bit more booty with plenty of sustain and they seem easier to start with the bow than the spiros. I've done a search but couldn't find anyone who had used these strings until they were worn out. I'm curious as to how long I can expect to use them. TI's site says they don't last as long as steel strings but considering that spiros still sound ok after several years this could mean anything.
