My compliments Mario on a very well written and informative review of your MFR. I've made some similar findings with my .20 MFR. I don't bother with the single shot loader either, finding it easier to thumb a pellet straight into the breech (although I could do with one for my Rapid 17 Mk2, as I just can't get my fingers into that slot).
I have exactly the same scope on my MFR and feel it's too high. I need some 30mm mounts so I can try my Nikko 6x44 on it.
Unlike yours - my trigger was creepy. Ben Taylor has just adjusted it for me and it is now perfectly predictable, although - like yours - the pull is slightly heavier than I'm used to.
Accuracy has been good with H&n ftts but not exceptional, but the creepy trigger may have had something to do with that. I look forward to future tests.
My stock isn't just well-figured - it's breathtaking - the best I have ever seen on a Rapid.
Like you, I love owning and using this rifle
