For me it’s all about filling my hand out in the lower positions -helps with playing comfort. Up high I don’t prefer it to be hugely big -just a bit, as my hand position is different and likelihood of having to hold a chord for a period of time is less. Part of the frustration with EBMM is they build just as good as Suhr and Anderson but never offer the same range of options. Which is their prerogative of course. I’m a huge 1 5/8 fan as my favorite necks of all time are 70s fenders on the chunky U side.
