Hi there M1964,
As someone who finds the BD5 quite playable initially, and tiresome fairly soon after, we might be "in the same boat" (or at least a similar one).
- It's no secret that the resistance/hardness of a mouthpiece is the result of many different properties (as said above, rail thickness, baffle profile, throat etc all come into play).
- in theory we should be able to adjust to different "hardness" by just using a softer reed but it doesn't really seem to work that way as our playing/embouchure interacts differently with resistance in different parts of the set up....
I call this the "resistance profile" and find that two mouthpieces can have radically different tip openings but still be quite playable for me as long as the share a resistance profile.
As someone who has done a LOT of refacing over the years, I can also testify that a small difference in the CURVE, and/or the interior of the mouthpiece, can make a big difference. Bear in mind something that seems a SMALL DIFFERENCE during the initial notes, can become a BIG DIFFERENCE over 30min of playing.
EXAMPLE- mouthpiece refaced for an NZSO player who loved maximum resistance and super hard reeds. He moved on to something else, a colleague tried out the unused mouthpiece and loved it, but always felt they were having to work a little more with their embouchure to get articulation to work. Taking some excess material out of the step (thus deepening the throat without widening it) was enough to loosen up articulated notes for this player (it also robbed a little of the focus in the lowest notes of the range, but not drastically).
So how does this all relate to your OP?
I would say that from the 3 mouthpieces you mention, you'll find the M30 the easiest to adapt to.
The M15 I like, will need slightly harder reeds, but will also be a LONG WAY in the other direction from BD5, you will get a lot of freedom but not much security.
The 5RV Lyre, I think SHOULD be a good mouthpiece but I always find the CURVE too stiffling... a fraction more length to the facing and small adjustment to the curve and these can sing.
I'm probably an outlier on the 5RV Lyre- I basically think it *should* have a facing like the D'darrio Evolution and change it to that. Others might say "just buy an evolution then"!
I reckon you'll like the M30 though!
