This was covered in another thread.
It seems that using the Moki, which is a little heaver, helps the tail heavy condition ... if not eliminate it.

I am using a Saito 180, and need to add 7 to 8 oz. in the nose. (check the weights of your choices for comparison)

However ... weight is weight, whether its the engine or lead. ( as determined in the other thread)

I think any of your choices will work.
The Moki will require a longer break-in !

Hope this helps.

Good flying to you !
