Yup. Many players who don't have small stage issues cannot relate to the huge benefit of having even 4-5 extra inches on stage. I have played many, many times where there was literally no more room on either side of my keyboard. Compromising stage area, means compromising performance. Dealing with a few less keys is a workaround ... not a compromise. With octave shifts, and custom sounds, there is no reason to feel cramped playing on a 61 note board. I play so much manual bass, I split my kb at Eb above middle C, so my chord hand has only a little more real estate than my bass hand. RH goes 2 octaves + a Msixth, LH is 2 octaves + m3rd. It makes playing interesting bass lines easier, and also keeps my hands centered on the keyboard. If the split point was any lower, I'd be uncomfortable reaching my right hand across my body to access those lower notes. I almost alway have my RH sound tuned down an octave (to better compliment my voice). It's so easy to hit the 8va button for special solo sections, if needed.
All that, plus the ease of transporting a smaller KB, fitting into my trunk, on hand trucks, etc ... make using anything BUT a 61 a no brainer. We're all different, but these are my top reasons. (was this on topic?)
