Hello Mr. Grungy.
I`m making this post to give you my feedback, based on my own personal experience using two long throw machines: BOSS G15 and RUPES 21 MKII
Quoting you from this thread: http://www.autopia.org/forums/detai...i-hd-version-shot.html?highlight=#post2089735
"Curious as to the selection of the 15 vs the 21. Was it only due to cost of the machine and materials or something else? I too am considering a large throw machine and am looking at both BOSS and Rupes. 15 vs 21 seems to be the real crux on either one as I have a huge SUV and Taurus but those are my only vehicles. Anyone with both 15 and 21 machines care to give feedback on which one you would keep if you had to make a choice? This has been talked about before, but interested now that both have been out there for over a year or two now."
My Thoughts / Exprience - I received both of those machines back in December. I tried them side by side as soon as I could. On the hood of my Yaris, the "center" section of it, the halfway split measures out to about 18x18.
Initially, I wanted to make a comparison as fair as possible, try to get apples to apples. To that end, I was looking to use Rupes UHS on both machines. I planned on the 7" UHS pad on the Rupes, and the 6" UHS pad on the G15. It didn`t take long to throw that idea out. WHY? Well, if these machines were designed, and then pads designed around the machine, then it would throw off the results. The Rupes pads are quite different. Even comparing the BOSS 5.5" pad to a Rupes 6" pad. Pictures below will show what I mean

I took the BOSS G15, a BOSS Yellow 5.5" Pad, and the Perfecting Cream on the left side. On the right side, I used the Rupes 21 MKII, Rupes Yellow 7" Pad, and their Keramik Gloss.
This wasn`t to test which is faster, or which corrected/finished better. Rather, it was to get a "user experience" using both machines. Back to back. Side to side. In fact, I went back and forth several times. Both machines felt good. Both felt smooth. It was a wash. (just to note, both finished out the same. I couldn`t see a difference in the paint).
I did manage to stall both machines on the same spot, where the hood transitions over a bulge. What I did notice here, though, it took more thought and different approaches with the larger throw of the 21mm. I`m guessing due to the nature of the stiff Rupes pad, coupled with it`s increased diameter, it sort of "bridged" between the flat part of the hood, to the higher portion of that bulge area. So there was about a 2" strip of untouched paint. I`m not sure I`m making it clear. There was a section on the hood that wasn`t being touched by the 21mm if I went straight left to right, or up and down. I had to tilt the machine this way or that way, do edgework, etc, to polish that area out. The 15 sort of floated over the same area on the opposite side.
This came to show me what I was half expecting. The 21 is a nice machine, but I`d use it for larger and more flat areas. So, if I had to choose only ONE machine, I`d go with a 15mm.
Now....what about Griot`s vs Rupes? Both are great machines. It would come down to personal preference. It really would. For me, the number one factor is cost. Cost of the machine, pads, and polishes. Another, and quite unexpected factor, is the size of the pads! BOSS pads are so thin. Rupes are about twice as thick. Stack 6-8 Rupes pads. That takes up a good amount of space. Stack 6-8 BOSS pads, and you`re using half the space. And since I`m running low on space quickly, the thinner pads would be welcomed.
Here are some pics, with various measurements and weights. To ME, these can be important. I`m 5`6" and use Medium sized gloves. How is that relevant? Shorter wing span, tighter hand grip. The distance between the grip on the head of the tool and to the trigger handle can make a difference to me. Not a huge one, but enough. I noticed this the first time I used a Megs MT300. The hand placement threw me off (from using PC style machines) and I noticed during a test session, that the lower part of the hood wasn`t being polished. The lower hand placement near the trigger handle messed with my muscle memory, so when I got to a certain point on the panel, I thought it was at the edge. That`s my theory, anyway
I had to adjust for the different arm distance gripping the machine.
The grip is also important. With my grip, I prefer a smaller grip, as it`s easier to hold. Less fatigue. Plus it`s more natural to hold something like a trigger handle, vs a tool body.
Here are those pics I mentioned. Sorry, I keep on and on.
Weights:
-Rupes 5.8
-Griot`s 5.9
Honestly, though, the Rupes feels a good deal lighter. When I pulled it out of the box, it felt light. So much so, that I had to double check to make sure it was a 21mm. Then I had to make sure it was the MKII. It felt lighter than it is.
