hey Eric,
Just to let you know, I'm getting some of your IB38's off of colin to try... badly need new batts at the moment, seriously suffering a lack of punch from my (very) well worn GP33's.
Quick Q, any tips on how to store/charge them? Going to mainly be doing 19t this year, so I'm thinking 6A might be a bit high (it's what i usually charge at atm).
Also, what you doing up so late? it's almost 5am here....
