Well, at the moment I'm playing an Olds Recording. There was a bit of a convoluted trail to that one. I was playing a Bach 37 (I am primarily a lead player in a big band) that I had since the end of high school. I bought a Yamaha Mike Vax to replace that. Then I switched mouthpieces from a Marc. Vizzutti model with a bored out throat to a GR 65.6S because the Vizzutti didn't work very well with the Vax. Then I started to find the valves on the MV a little too squishly feeling compared to the Bach valves. I started reading about the Olds horns on Trumpetherald and discovered Ebay. That was bad news.
Specific to the Recording, I love its unique sound. The intonation is great. It's a really powerful horn and it slots really nicely without being too 'stuck' in each slot.
I would like to try a vintage Benge 2x or 3x and the more I read this forum, maybe a 1s2 for a bright horn. I am also thinking of re-engineering my Ambassador with a Pilczuk pipe, just for fun.
