Cav/arch from inf/Cat transitioning

It won't be difficult transitioning troops cropwise, because you are killing troops which offsets your building troops, the real hard part comes when you ARENT killing troops and you keep making troops XD and just in case you want to know, you usually need an average of 8:1 to 13:1 archers to cats ratio for clean kills by the archers, depends on how much attack you have and defense they have 

Im on s57 which is only 4 days old and im ranked 2 with 140k pres and then next closest people are around 70k (that are attackable aka not in my alliance) So my main concern really right now is clean fort fort farming and Im sitting at 5k cats. So would it be a good idea to start the transition or should I wait a while until im farming lvl 10 forts and so on and so forth.....

And also I would like to know if someone who is a very experienced player to be my mentor? I have pal and we could use that for quick communication just to help guide me and make sure I dont make any stupid moves.. lol

feel free there is a group called haypi s23 if you join it and add me as i am the owner of the group you can talk to me anytime and i will try and help
