In trying to be an ass, at this point, several things occur to me......
One, this thread could become very valuable in terms of future assistance and reference.....
Two, Direct Drive has done some of the tightest, best drilling in Weber metal I've seen anywhere.....check this addition of a Tel-Tru with bezel in a kettle :
http://weberkettleclub.com/forums/weber-kettles-accessories/lid-therm-mod-for-kettle/msg108306/#msg108306Three, trying to control temperature in an extremely tight fashion is the surest way to destroy enjoyment of a BBQ experience that I know of......
-Time after time I see people getting nutty over minor swings in the temp.......it's the nature of burning fire, charcoal, wood products.....to light, heat up & at some point begin to fade & dissipate.
there's a big discussion @ Bretheren right now about "When you started Q, what was your biggest challenge?" 20 of the first 24 responses are basically: Don't fret or freak out about temp swings......I've seen more or less the same conversations at Smoke Ring for years......
-The only real trick to it is being mentally 'in tune' with your fuel source & the cooking machine enough to understand approximately where you stand at any given time.....
- Your home oven swings in temp as it cycles on & off around a set pivot point.....back & forth, up & down.......stuff still usually comes out pretty decent, even with all that goes on there...........
-The air gaps that the Bman noted are something to consider......my sense is if those gaps were to have a major cook-destroying effect, Weber might have already addressed them in the area of design somehow....
Consider this :
Tool hooks, condiment racks, side tables.....all pretty coveted accessories as far as I can tell from what folks say about them (generally speaking, maybe not everyone is thrilled).......what about the gaps created there?
I'm sure they have some effect, just from my own fairly minor experience with them.....
The sense I get there is that fuel & setup, including intake vent settings are just a bit different using anything that allows some air through from any point.....again, "only real trick to it is being mentally 'in tune' with your fuel source & the cooking machine enough to understand approximately where you stand at any given time..... "
My only Performer doesn't have the gap for the gas assist tube, but it seems that's a decent size air gap right there on most Performers..........how to deal?
Compensate by way of fuel setup & vent settings, I would guess......people who are really familiar with those need to chime in here.....do you have trouble shutting down entirely because of the air leaks?
Anything majorly noticeable?
Now, to the idea of the Maverick in the first place.......these units are to be set up as a parameter thing, right?
To aim for a window of high & low, with some kind of alarm to alert to too wide of a temp fluctuation?
Or is it more like just a monitoring so one can check in more easily from time to time? Or both?
I need to get this understood maybe a little better, as I have one but it's never been out of the package.....saving it up for the big cured sausage debut, I guess.....there's a place where a tight temp control is necessary....too fast of a rise & you melt out all the fat & have dried out links....not a correctly stepped rise in temp & I guess your run the risk of not working the cure well enough & having it goofy the other direction.......
School me up on the temp control idea using the Maverick, as i've only started using thermometers in the last few years & don't maybe totally understand the whole concept......
