Anytime Harry. I usually sail solo and, since purchasing my H16 5 years ago, have upgraded it every year. Usually just sail the 15-20 knt days trapped out pushing the boat as fast as it will go. There's lots of upgrades, ideas, etc that you can do to your H16 depending upon you needs/wants, etc.
My boat is up here in Montreal at the moment where I sail Lac St Louis. Not sure if I'll be down to sail L Champ again this summer but will be happy to return mails and pass on any ideas you want/need to enjoy your H16 - a great big wind boat that handles the L Champ southwind waves without a problem. I'll take you across the lake and back on a screaming beam reach next summer and you'll be hooked for life!!!
If you're not used to screaming with your H16, it might help to join me one day - speed up the learning curve, etc.
And traffic will no longer be a problem with your H16 - you're usually one of the fastest boats on the lake. After 5 years of sailing L Champ I can say the seeing other cats is uncommon and I don't know why - great lake to sail - deep, no weeds, and the south winds are steady and wild!!!
Have a great sailing summer
