The Booster Wheel arrangement has been the same for quite a while.
With the Coconut Wheel and Colour Bomb on either side of the "Jackpot", those invariably are the ones it stops at when you're think it's about to hit Jackpot.
Why not have a rotation system, by mixing it up for a period
Eg, Lollipop Hammer and Free Switch on either side of the " Jackpot", for a period of 3-6 months or longer.
LH and FS would be a great consolation for many a player.
You read about the amount of Coconut Wheels that players have and hardly use. CW's are great when one can use it in a level, but those are not frequent.
