speed tune is a scary term for me = lots of work  .....just being honest
I speed tuned a unkillable  CB team one time (I have 4  maneaters)  and honestly it was hard  for me to make it all fit together with gear  .  Did  it though and then  picked the  least set up team possible (3 turn set up).....worked for my early account
But hated the set up  = just rather throw together a team and  auto it (watch YouTube while on AUTO) . So now 1 key NM and 2 key UNM  with auto and watch YouTube
So more to your  point.............I know I own champions to do much about  this game .....but.......I am ssooooo  LAZY  I do not  invest the time/research needed to do all the work  and lets be honest ,  at end  of day likely do not have the gear (because I am sitting on 140K energy and not farming gear)
So for  me being able to throw together a team with what I think is the best gear I have (I know the principles  of  play)  and trying it  = hope for best.  Is my best result  :(
So with respect I understand your helpful advice. But for me .......not going to speed tune any  Iron Twins team  on my account because I do not feel its that important and satisfied with my results either way
Like TRIPS said....Just buy a  new set of Golf Clubs and see you next week....LOL
Thats me and this game =   But LOVE this game....really do love this this game  :D
