Difference Blue Obs vs Pro Obs?

[Crypton]

I'm a little bit confused by the describtions of the Blue Obession and Pro Obsession Special.
Am I correct in assuming, that the Pro Obessession Special has the same maze as the Blue V1 Extreme with the (red) V2 Sleeve?
And the Blue Obsession has the Blue V1 maze, which has to be completed 6-times and the (blue) V2 Sleeve?

I do understand that all Obsessions have a plastic shaft.

Extreme:
- Plated brass maze and aluminium sleeve

Obsession:
- Plastic maze and sleeve

Obsession Pro:
- Plastic maze and aluminium sleeve

Hello!
The Blue Pro is an Obsession (all plastic) with the Blue maze design that has to be solved six times. It has a red sticker on the end of the core. This core was used in a V2 sleeve (metal, different design to the regular Extremes) to make the special. That makes five official types (cylindrical, regular size, R1):
V1 Extreme : metal core, ribbed metal sleeve
V2 Extreme: metal core, no drawbar, smooth metal sleeve
V1 Obsession: not removable plastic core, plastic sleeve
V2 Obsession: removable plastic core, plastic sleeve
Obsession Special: plastic removable core, metal V2 Extreme sleeve. (The Blue needs to be solved once, the red Pro needs to be solved six times).

Early on the usage of the names ‘Extreme’ and ‘Obsession’ was swapped which might cause some confusion.
Cheers!

The first Blue Obsession Pros were made to match the style of other V2 Obsession puzzles, with a removable plastic core and plastic sleeve made in the style of V2 sleeves.
