Different tools for different purposes, IMO. I have an HK feint which is similar to an RTak 2 and I like it for faster hikes where there may be some trail clearing but it's limited. It's quite light, clears vines and small limbs easily but I can still clear up some downed trees/branches if they've fallen over my bushwhacked trail I frequent.
I carry a machete for heavy cutting days but it's either 14" golok or a 20" panga. I don't think a thin, short machete would be my cup of tea as it's still limited in length meaning I have to bend a lot to do what I want to do. I'm also curious if there is too little weight towards the tip to carry through tougher objects, unless everything you're cutting is pretty soft.
I find it interesting how many people complain about machete sharpness out of the package. Sharpen it, problem solved. It's apparently a practice in Latin America where many are made to send off machete's dull because the purchaser wants to put their own edge on it, or the manufacturer is saving money and doesn't want to do that part. Still, easy fix and factory sharpness should never be used as a measure of a bladed implements performance out in the world unless you do not sharpen your own tools.
