Mark IV vs Triaxis (I've been offered a swap)

I own a early model triaxis/290 combo. Had it for years, and been very pleased with it. Recently I've been wanting to go to a 'analog' setup for simplicity, and ease of pedal tweaking (I'm running a gsystem with my triaxis), and got an offer of a straight swap for a mid 2000's mark iv head. Just wondering if anyone has thoughts on the mark iv heads, and how they compare to the triaxis? (Mostly, I'm just super ansy to get my hands on this, and need conversation to keep me amused while I wait)

I had a Triaxis/2:90 and hated it. I think you will love the Mark IV.

I hope so! That swap fell through, but I'm trading for a 1991 mark iv a compact combo tomorrow
