Suggestions for a new toy

To start i would like to say the model i have is a knock off. Something i bought off adam and eve thats shapped either like the MGX or Maximus. I havent measured it so im not sure which one it is modeled off of, since its a knock off its very likely that its a combo between to the 2. Anyways with ive achieved some great things. However I feel like there is more that i can discover and looking for a new model has proven to be tough. I feel like the model i have now is not quite full enough and its movements isnt the best. Which brings me to the cross road of whether or not i should go with a heftier model or go with a skinner model like the eupho. While id place myself and intermediate level, i have super os but not on command and im certainly not a-less yet, im not sure bigger would be best since i enjoy the little movements. As you can see im torn and any help would be appericated.
