If you have the funds you can buy a few and send them back if they dont gel with you. Many makers have decent enough return policies. Just pay for shipping and they will refund the mouthpiece cost.
Even if you COULD get to a festival, this might be the better option, if you are really serious. As Geezer notes in a later post, it takes more than a few minutes to try a mouthpiece. This is ESPECIALLY true in the bruhaha of a festival vendor area.
Your "soft machine" will adapt to almost anything. Unless you play the mouthpiece for some number of days (that number depends entirely on the player and how easily they "give in" to new equipment) you will get many "false positives" and probably as many "false negatives."
I have heard more than a few players come into ensembles with new mouthpieces (horns, valve covers, counterweights, bell wraps, etc. etc) and sound different the first week and then, after one or two more weeks, sound JUST like they did before, except that their endurance went down for a while. It usually took a week or two after THAT to figure out if the endurance would get better than before, or worse, or the same.
Best is a guided search with a good teacher or specialist like Elliott or Wilken as noted above. But in any case, the most important element will be time.
