Not really...

If I want to build below .15, which I don't often anymore, I'll only use my VTC series cells, but for most purposes a set of 30Q cells will do ya more than fine ;-)

BTW, aftermarket testing is showing that 30Q cells may very well be 20A continuous capable just like a 25R.

I have taken them down to .19 with no issues whatsoever (just under 20A under load).

Vdrop gets a bit extreme lower than that, IMO meaning .2 is a good number to stay at or above with them.
