I think many of us are aware of the usual advice given that you must not use a reed to playtest a mouthpiece if it has been used on another mouthpiece. This is sound advice when a reed has been well "bedded in" to another mouthpiece especially if (a) the facing curve is a smaller radius and/or (b) the tip opening is wider.
HOWEVER
Many of us find this totally impractical because you want to level the playing field, ie see how the new mouthpiece compares with as many common denominators as possible - otherwise the different reed could be skewing the results of your testing.
So here a a few tips (pun intended) on how to proceed

So here a a few tips (pun intended) on how to proceed
- Avoid using a reed has been played a lot on one mouthpiece, although if you know the facing is very similar it may be OK. (That does not just mean the tip number is the same, you have to be sure both tip and facing curve are the same).
- Using a new reed that you may have only played for a minute or so should be OK. If you have several mouthpieces to try don't play on one of them for long than a minute or so.
- Have a few reeds lined up ready that have only been played a minute and make sure they all had the same sound and response. If you believe a reed needs a lot of "breaking in" this method may not be a good one for you.
- "Level up" a test reed by bending it the opposite way to the curve it has adopted. This can work with synthetic reeds if warmed up in hot water. Beware doing this more than a very few times as it may well degrade the reed.
- If all else fails and you only have one reed try the above , just go for it. Even if the used reed may give you a false idea, often you can just tell by intuition that in spite of the used reed, the new mouthpiece is either a dog or a holy grail. The worst that can happen is you buy the mouthpiece and no return policy.
