For every hour you lessoned with a coach, some amateur has put in 3 or 4 hours practicing, so you are probably newcomer level (but your 'pro' dancing was at a higher level). This is due to the fact that dancesport is a peer to peer sport; an artform/sport that takes training and skills that take time and repetition, and not something you do an hour or two a week.
If you 'try out' with a beginner man, he will of course not feel like your coach, but he WILL be at your level - think of it as a 'reality check' that that is the way YOU feel when a high level leader dances with you. You then will see that you have lots of work to do. And then - go witht he beginner man. He's really at your level, and you will progress very quickly when you have a partner to give YOU feedback and train with.
Don't be discouraged by this commentary - many folks look at pro-am as simply a nice diversion ala 'pottery class' or some such diversion - so you are going to have some bumps along the way (the amateur partner, for example, does not have to tell you that you are good, but a coach needs to make you fell good to keep the lessons going). it is infinately more rewardingm though, to dance well...
