Dr, even though I complained about getting used to the selmer ergos in another thread, I want my backup horn to "feel " like my main horn. This P is a good tenor but my 6 had an unexpected problem right before a gig a few months ago and my wife rushed the P to me at the gig. It took a good set to get used to the difference in the Ps response and feel vrs my 6. So, I'm hoping to pick up a back up and just play without the learning curve. I was thinking a Series 1 or something like it but I'll consider your suggestions. BTW, did you sell your Ref 36? K (PS, the P has one and half times the body of tone that my 6 has and is a "fast" horn but I'm locked into the selmer core to the tone. I did get good results a couple of years ago from a Couf superba II but the palm keys were way flat to the overall intonaton on the horn and I got tired of having to adjust all the time. My Mk 6 is very well in tune compared to other 6s I've owned. ) K
