(DA) 8mm standard throw vs. 12/15/21mm larger throw

[VISITOR]

does anyone else think that a bigger stroke isn't always better. for example, if you had a little scratch/scuff on your paint and rubbed it out by hand with a foam applicator and polish/compound with quick 2-3 inch strokes as opposed to 4+ inch strokes the defects would probably come out quicker because you're using small/quicker isolated strokes to remove the defects..

you would think the new megs mt300 and torq10fx DA's would be offered with a larger size throw but still use the standard 8mm throw like most other (traditional) DA's and still do an excellent job even though we all know pads, liquids, and technique play major roles as well...

just thinking out loud hear and would like to hear and welcome everyone's thoughts/opinions on this....

I think the new machines are 8mm throw because it prolly takes mega $$$ invested to make a large throw machine that is smooth and balanced like the Rupes and doesn't shake itself apart.

CGs & Megs don't make tools. They are contracting this job out. Rupes has been making tools forever. So they have the knowledge, testing facilities, and tooling to design a tool like this completely from the ground up.

The rest are just a smoother PC with a copy cat Rupes body IMHO.

The new Megs machine is on VIP for $199

In your example:
What are the differences, if any, between the
"scratch patterns" that are left from the: by-hand-technique's 2"-strokes vs. 4"-strokes...when using a compound/polish on a _?_" foam pad?

Going with the results from there...
In your opinion:
Would castling the above bias/approach into using:
by-Polisher-techniques with Polishers having 8mm stroke vs. those having 12-15-21mm strokes, on the same sized (_?_ ") foam pads, be of any consequence for comparison?

Pig Tails left by a Rupes are more flowing and beautiful than those left by the Brutish Flex 3401

Whether polishing a single defect or. Anentire panel, what's most important is knowing what your doing and what your working with. I regularly polish granite countertops in people's houses, who have a hairline scratch running through their natural stone tops. In this instance, limiting the amount of material you touch with your first step is absolutely critical to not only how long you will work to remove the defect but also to how effectively you can consistently polish the area to match the surrounding surface.

As far as paint goes, blending a worked area with a properly polished panel should be cake. For my day job, a 3" rotary diamond pad is what I'll start with when doing onsite repairs. For paint, the thought of using a machine or pad that uses an inch or even 13mm less than what I would usually use to polish an entire panel instead of focusing on a single defect is absolutely irrelevant IME.

flex would of jumped on the larger throw bandwagon if they felt it was necessary, yet they still have the 3401 with the 8mm throw. having the interchangeable backing plate with use of smaller 4" pads and still be smooth as it is, i'm wondering if a few mm's more would make that big of a difference where using smaller pads would effect it's performance. also, megs if i'm not mistaken built/designed their new DA from the ground up with the assistance of the tool company producing them. it lists for around $300 and i'm sure if they felt the need to go a bit bigger in throw, they would have. who knows... thanks for the replies thus far everyone...

Was it your interpretation that the OP is polishing an 8-21mm area?

I couldn't sync up your response with the OP's question
