Steep approaches are good but it requires vigilance of picking the correct sight picture - again, for the B412 the pitot tube method seems to work well.
The main thing for these types of approaches is the momentum from a too high rate of descent. 350 fpm max. IMO.
If you stuff up the angle and rate of descent then it could get nasty at the end (where it counts).
The B412 Classics will obviously react a little less spritely than the HP/EP.
