I know that John from Refined Audio has said he slightly prefers the 8" over the 10".

Another avenue to consider is using the 10" with room correction software.  I have 10" Nenuphars in a relatively small room 13 x 15 x 10 and think they work great, but have noticed that some mid to lower bass notes get muddled (I have no acoustic treatments other shelves of records).  I am going to borrow a Dspeaker anti-mode x4 to see if it corrects this.  Won't happen till late July, but I'll report back.

Thanks for all the replies.  I had a strong feeling that most would recommend the 8".  I had my heart set on the 10" but room changes dictate looking at the smaller option.  Will also look at the 10" small monitor.  Btw flooring  is suspended with carpeting.

@stephendunn There are certainly posters out there who's ears I trust that use and enjoy digital correction.

Unfortunately my only experience was *not* good. I had a Lyngdorf tdai-3400 for some time and turning on room perfect kind of made me sick to my stomach... the music sounded "blended" for lack of a better term. Definitely less natural than without.  I had the amp for about 6 months, so I knew it well and had obviously done RP setup many, many times. Just couldn't get it to sound right with my Coincident PREs. Every time I turned off any form of digital processing it got better actually, but never quite right.

Very curious to hear about your experience and add another data point.

Bob, you will probably need longer spikes if the carpet is thick, in order that one maintains the gap as intended. Or arrange for them to stand on something solid.
