I had a 7A and flew it in IMC without issues (crashing) but it was a bit of challenge for me. I would be a total worked out during instrument practice and more than 4 approaches in one setting would have totally tired me out.
Now in the 14A, though only one year experience with, I find it much easier to do IFR. I have done only two approaches in IMC but the practice runs are much easier and less of a work out.
I hope this helps.
