Welcome newcomer. If you've spent any time on this forum, you'll know that the question of "first khuk" is more or less useless.
I once posted this conundrum, foolishly thinking it'd be my "only one."
And four khuks later, I'm waiting on my fifth, a custom knife.
I have an M43. The handle and chiruwa style tang is all a bit much for my hands, which are a bit small for a man of 6'2," and for that reason I'm inclined to recommend an ang khola.
Really, though, the two bullet points are 1) warm welcome and 2) you're going to get both within the next couple months, whether you can afford it or not. These things are hand forged crack.
edit: I don't own an ang khola myself, but my other two full size khuks both have the partial tang. The feel of my 16.5 WWII makes me suspect the ang khola is a lively and handy khuk in the hand at a 15" length.
