Bloke/Houser Helleberg rims in Chicago?

[chronolith]

Trialing mouthpieces and rims through the mail can be a pita.

Is there anybody in Chicago who uses the large and small Helleberg style rims with a Bloke or Houser mouthpiece? I would like to try them out if possible. I currently use the excellent Modified Helleberg rim but I really want to dial it in and ensure I am using the best tool for the job. I have a couple of #2 rims that I can offer in trade if you might be looking for something different.

PM me if are willing to let me have a go.
