Interesting, my old clear reels work perfectly on the new(er) 1500 system tank. I don't rotate so I don't care anyway, but just sayin'.

I have several of the older and newer reels. I find the old, clear ones vastly superior to the new opaque versions and almost exclusively use the old reels. The reason being the larger film guides of the older versions which make finding/feeling for the starting point so much easier in the dark and the film can't "jump" out of the larger guiding area - something which can happen (and has happened to me on occasion) very easily with the new reels, especially when using PET-based films which have a higher resistance.

I have both styles but prefer using the newer ones, I also had the core of a Paterson 2 Reel tank reduced to allow the reels to fit, as if I am doing semi-stand processing I prefer using the Paterson Super System $ tank as it sits nicely in the hole in my TBE.
Another aspect is the change of materials.
With a report on static discharge between film and reel on a Paterson reel in mind this could be an issue with Jobo reels too, and than there might be a difference between old and new type reels.
As far as the different materials, the Clear reels may be more subject to cracking, although the only clear jobo that I have broken is the top part of the dedicated reel in my "Jobo-Triumf 35-16" tank. (that particular tank can be adjusted to do 1 roll of 35 or one roll of 16mm/110 size film.) I do have a couple of the newer style where the center has broken off the tab that locks the two halves together.
One Very Important mechnical difference is that the older style reels can be set for 127 Size films, but the newer ones are only good for 120 or 35mm
I still live just beyond the fringe in Stittsville
-) the old reels aside of type 135 and 120 also take type 127 film
-) the new reels might take type 127 if one cuts off the teeth at the reel shaft used for type 120 and engages the teeth for 135 at the smaller slits. Maybe those teeth have to be made smaller.
(I have not yet tried this modification especially not for the play for type 127 film, maybe someone reports on his attempt.)

I have the newer white 1500 reel designed for 35mm and 120 by pulling it out to it to the outermost dowels on its shaft. One half of the reel has a lower inner groove with the hole for the red spacer for developing two x 120 films on the same reel.The other half has both the inner and outer grooves level. It doesn't seem to matter which way I place the reel onto the centre tube but is there a correct way that it is supposed to go onto the tube i.e. should the level grooves be at the top and the indented groove at the bottom?
To my understanding it makes no difference how you orientate the reels on the spindle.
The only issue I see is the way the reels turn through the processing bath (with or against the grain). But this rather should be a theoretical issue. And a no-issue with reversing processors anyway. I never ever saw this oriention issue referred to before.
