Is the 15450 the next big hype?

[TooWoundUp]

I first became interested in the 15450 about a year ago because the size seemed like a better option than the very large 41mm 15400. At the time there was hardly any interest in it, and used examples were going for as low as 12k!!! However in the last six months prices have gone up more than 50% and I see multiple posts a day about the 15450.

Curious to know why the surge of interest in the 37mm => I guess the 41mm are becoming unattainable. But you can still get good 15300s and 15400s for not that much more. Interested to hear thoughts.
