You told me a while back that the 8v needs an hf im, whereas my b1 requires an si im. I also vaguely recall you saying that the b2 takes the hf im, even though it is a 16v. You had said that it was closely related to the 8v, whereas mine has compatability with the si.
If this is true, then i need an si im, but switch to hf im when i go 8v. whew.
