hahahah. agreed, that quality tools are key to getting the job done right. i did bump up to the E6 by selling my WSM 18 and my old Summit 620 (and a few other household items to get my purchase down to zero new dollars spent).
conversely, one can give an E6 to an inexperienced backyard bbq'er and get garbage results. so the E6 as a tool has elevated my game, bigly, but my core skills enabled me to reach my current level (whatever the heck level that is). and i'd say the E6 has even advanced my skills level. my ribs these days are 1,000x better than when i was WSM 18'ing them. the 24" real estate, diffuser plate and dual wall insulated construction are game changers.
i was trying to buy the original Summit Charcoal used off Craigslist but the only one i ever saw and was about to buy, the seller bailed last minute and decided to keep it. so i just said funk it, and paid the price as my Father's Day gift to myself. i seem to always buy myself the best gifts; jajajajajajajajajajaaj. and the family likes it too, a lot!
