I am just suggesting to TS, try working with 1 at a time and realised what it brings, since TS has no idea where to start, what to shoot and how he/she wants to shoot. I guess only when you truely understand your own equipment, then you will be able to make informed decisions on what to use. Like what you have mentioned "You choose the tool (lens) to suit the requirement"
. 1 month is just a guage, it can be longer, it can be shorter, most importantly is to realise what that piece of equipment bring to you or not able to. After that, TS can slowly remove things which he/she thinks not necessary or doesn't suit his/her style of shooting. Just my 2 cents as a newbie
