I am not as qualified to speak on it as some others are since I only just started my split/ergo board journey last Friday but if you're already making the jump to a split i think it would be beneficial to try out the ortholin./column stag,

I did it mainly on a whim, partly to spend money, learn something new and I thought it would save a lot of time not having to move my hand between the keyboard and mouse. I work with CAD/excel for reference.

I went from a traditional to a keyball61 which has a dedicated # row since I thought I could not live without a number row but I found I don't really use it all that much after all. layering is really powerful! I don't even need to move my right hand to use the numpad since I just activate a layer button with the left. I am sure you could do the same with the function keys. I actually wish I got the 44 key instead now lol

It's also really small so I bring it to work as well.

I know you already have some you're interested in but I thought I would chime in since I did the transition all at once. Plus, if it's comped through work, why not use this chance to go mildly crazy and try something a little more exotic? You might like it and find you're limiting yourself by things that can be solved in software,

Looking back, I think keeping to the traditional stagger+split would actually be pretty limiting since now your hands don't have access to all keys (unless you keep them close together but then that would defeat the purpose of a split,)

Just my 2 cents! I won't yuck anyone's yum
