Formerly Sporasub Stealth = recently Sporasub Spark mimetic = now Mares Spark mimetic. The main difference between these and Seac Asso is the barrel diameter 11mm in the Stealth/Spark vs. 13mm in the Asso.

In general terms, a 13mm barrel airgun provides for
-> more power as compared to an 11mm barrel airgun of equal length and at equal pressure, PROVIDED that the barrel is sealed with the Mamba kit (or similar) and
-> more shaft speed, PROVIDED you down-size from the standard 8mm shaft diameter to at least 7mm AND use a barrel sealing device.

An 11mm barrel airgun on the other hand is much easier to load and offers greater shaft speed on an airgun without a sealing kit (less water to expel).

Unless you are going to install a sealing kit IMHO the odds are clearly in favour of the Stealth/Spark mimetic. If you intend to install a sealing kit, it is for you to decide whether you value raw power over ease of use (and still plenty of power!).

Personally, I am using Mamba- / Kara-yo-kitted Stealths/Sparks 97 and 110 in the Med.
