Just like to add to the conversation: the longest any tag team champions have held the title has been 10 rounds. There are four tag teams that have hit this record (Full House Daves, Brothers in Arms, Runn Reynolds Runn & Action Saxton/Saboteur's [including Saboteur's solo run] 2nd reign). There a few teams who hit the 9 round mark as well. Then again, a majority of tag teams were only able to last one cycle (i.e. win at a PPV, lose at the next).
Also, it is a rarity to see any tag teams not only win the titles but successfully defend them as well. There are only a handful of teams to defend the titles once and only two teams in history to defend them twice, one of them being Runn Reynolds Runn who also hit the 10 round mark (so one could assume they were the best tag team in history?)
---------------------------------
What I can deduce from this information:
- It is difficult for two (or more) individuals to synchronise for more than 2 months.
- New tag teams establish themselves and bring fresh ideas/become "flavour of the cycle" teams.
Every tag team champion succumbed to one, if not both reasons listed above.
I can confirm this as a tag team veteran in WZCW. Teach N' Kurtesy fell to the wayside due to reason 1; Crashin Movement won and lost the titles due to reason 2; Fairy Glitter Armageddon came into WZCW at the wrong place, wrong time so a mixture of both reasons; & Sloan/Taylor gained momentum but it wasn't something we wished to pursue as a team (reason 1). Cerberus is still going but I'm technically more a manager/singles wrestler than a tag team wrestler so results are best dealt with analysing Mussel/Ramparte.
---------------------------------
Speaking of Cerberus, should Ramparte (Spidey) & Flex Mussel (Dynamite) want to become apart of the record books, they must still be WZCW Tag Team Champions by the time Redemption is finished. Doing so will make them the first ever team to be champions for longer than 10 rounds and the third team in history to defend their titles twice (assuming they only defend at KC & Redemption)... a feat which will require 2 and a half more months to achieve! Going by the assumption in the parenthesis, the next title defense would be at Apocalypse, adding another 4 rounds to the record & another 2 more months as a team. If they want to be the only team to defend thrice in 1 reign, they'll need to win at Apocalypse as well.
On top of all this, you have to consider how long Cerberus has been around as a team and look at possibly making this achievements possible. It's a lot of time and dedication both members have to put into the team. Much harder than it seems on the outside.
