Congratulations! I hope you’ll enjoy the mikro when it arrives! I have three at this point In my (small-sample) experience the poly-coated basses weigh about a pound more than the walnut/weathered-black finishes, but this could be largely differences in the wood, rather than finish - I honestly don’t know. Regardless, mine all weigh between 5.5 and 6.5 lbs, including the Comfort Strappe I have on each. My most recent is a 2017 weathered-black mikro. No intonation issues at all with that one. As far as the reverse P goes, the explanation I’ve seen is that on such a short scale, it helps to balance the tone across the low and high strings. A regular P configuration on a standard scale bass slightly emphasizes the bass on the low strings, and the treble on the high strings. With a 28.6” scale, the position effect of the pickup (proximity to neck or bridge) is magnified. Reversing the P configuration adds a little bass back to the treble strings, by moving them closer to the neck, and helps keep the E and A from being too boomy, by bringing them a little bridgeward.
