weight - MP23 vs AT700

hi yall, recently i've been considering of purchasing a 3U AT700. Currently I am using a super fake - *Muscle Power 007* that i bought off a tiny store on the 6th floor of a random beijing shopping mall , so i do not think anyone has it to conpare it with the AT700.

But Having to have used a 2U mp23 in the past, I was wondering if the head-heaviness of 3U AT700 would make it feel the same/heavier than the 2U mp23? If not, does 3U At700 feel significantly lighter than mp23?

Thanks all for any information

 

thanks a bunch. am i correct to assume that a 4U AT700 would then be quite a bit lighter than MP23 and still pack more power than MP23...if handled properly?
