Hey all - I'm about to start construction on a Markus Jayne-style rack ( The Markus Jayne Rack) with 11" Flexwatt belly heat. I was wondering if anyone has had problems with tubs sitting directly on the Flexwatt - does sliding the tub over the Flexwatt cause premature wear/damage? Is it better to router a groove in the shelf for the Flexwatt to sit down in? Thanks for any input.
