Emailing Gene and Kristil is usually the best way to get answers ...
Yes, you do; 43mm (in my opinion) is vastly superior, especially when considering full-face gorgeous artwork. There are caveats, like storage, so keep that in mind.
I doubt it; DDLM 43mm's are considered to be full customs, so I doubt they have any hanging around. But again, maybe ask, see if they have some rejects you could get for the "feel".
That I highly doubt it. However, (and this opinion is probably the minority), I have samples of Chipcos and I prefer the standard blanks...
I sent an email when I ordered the sample set, which was almost 2 weeks ago and haven't heard back from them yet. Maybe it was just me being unlucky, or due to the holiday season. I asked here and got multiple replies in a few minutes. Thank you for the info, I think my main concern about going 43 over 39 is the big difference in price. I know I'll like them more, but buying 400'ish will add a pretty penny to the bill. I don't have any storage currently, so that's not a concern for me. Besides, with either size I'm also getting plaques. Those are my storage concern as they won't fit well in any cases I've looked at so far. And I'm considering getting both plaques, semi-customized. Which will probably mean a separate case to store them in. I should go check Youtube as I bet at least 1 user from here has made a video about this lol.
BRPoker will mail out generic 43mm samples for customer's who want to compare the two sizes.
Sometimes I overlook the most simple answer, any 43s would work perfect, thank you.
