If switching from poly to multifilament strings, is there a rule of thumb about how much tension to add to achieve somewhat the same 'feel' off the string bed? I say 'add' because conventional wisdom is that multis are inherently more flexible and resilient, and so, more powerful than polys. So one would naturally add tension to a multi string bed to preserve the 'deader' feel of the poly. Of course that specific # will change depending on the specific poly vs. multi. But what I'm looking for is an 'all other things being equal' number, if it exists.
