Would be very cool if there was a sand paper punch-plate that would cut the new Multi-Jetstream holes in to existing Jetstream sandpaper.

I have a whole systaner II full of the old style Jetstream150mm discs, several hundred. Most likely more then I will use in five years.

I can buy a new STICKFIX SANDING PAD with the new hole pattern, but I have $200 of old hole pattern jetstream 150mm discs. The punch-plate would allow me to punch the addition holes into the old paper disks.

 I have an old Bosh sander that came with a paper punch so you could use standard 1/4 sheet sand paper by using the paper punch as a size pattern and to cut the hole in the standard paper.

A paper punch for the Festool 150mm old style disk would only need to punch the additional holes.

I understand the cross comparability, which is great. I was just sad that I just bought the ETS 150/5 EQ and the systainer II of sanding discs last month (March 2010). and Boom this month I find out about Multi-Jetstream. I just felt a little left behind.

I come from the tech world where we always want the latest and greatest.

I have the 150/5 with the new multi-stream pad and I have used both styles of paper.  I cannot tell the difference between the two types.  I would not worry about it and not even think of going to the troubleof punching out holes.  In fact, I might buy more of the old style of sandpaper since it's on sale.

Same here. I have been using the new multi-jetstream pad now for over half a year and I see zero difference with the older pad and paper. The older paper is not on sale here but I don't care one iota which one of the two I buy. Most dealers here still have their stock of old paper and if that's what lies on the shelves when I get there, that's what I take home. There is no noticeable difference despite what Festool's marketing department says. So don't worry about it.

I also did what Bill Barker said above, some time ago, I stacked 10 pieces of paper on top of each other, put one multi-jet paper on top and drilled through the stack to make the extra holes. It works fine, in fact, in my opinion, better than a hole puncher. The hole puncher doesn't cut material away, it just pushes it aside. With a good drill bit, you get clean holes. But there's just no point to it. I understand that if you have no experience with the new paper that you think (as I did, it is only logical after hearing the sales pitch) there might be a noticeable improvement, but there really isn't.

 

The dust collection percentage is different.  Could it be the difference from the Rotex to the ETS or could it be the difference of the two pads with the different technology? 

Any difference you notice is most probably due to the two machines being different. They have very different characteristics. You can only make a valid conclusion after you use the two different pads on one and the same machine. I have the old standard soft pad and the new MJ hard pad for my Rotex, and I switch them out constantly depending on the application. If there is a difference between the two, it must be such a small difference that it probably only can be measured under laboratory circumstances and is not noticeable to the average user. 

Also, the new jetstream paper has a smaller center hole.  So drilling out the outside holes won't make them same.  Airflow might not be the same.  Maybe not a big difference but they made the center hole on the jetstream discs smaller for a reason.  I have a ton of the old discs and multiple pads for my sanders.

I'll just use them and replace them with the new style as I replenish.

I think the video is more of a comparison of the jetstream vs other conventional brands more then comparing festools new vs old.
