I am running the RimFire motor, but I went with a 1450KV rather than the 950 they recommended. I also use a 3 cell 2100 ThunderPower battery and the model balanced perfectly without having to add any weight.
And what is the weight of your motor ? If it balance perfectly with the 2100 TP and if your motor are not too much lighter than the bigger Suppo outrunner I may go with the second option. I am just a bit afraid of the complete flying weight.
* EDIT : I found your weight, it's the same 54gr. so my motor would be too heavy at 70gr.
