No need to apologize you've been a great help. I just didn't appreciate the runtime differance between the two until I actually started using it. Compounding my confusion/dilemna is the fact that DeWalt answered my email and recommended the NiCad 920KX kit for me given my usage patterns !!
Go figure right?
I was at Lowes today. I certainly don't want to be working w/ the 18V XRP nicad drill - its way too heavy for my needs and applications. The 920KX is noticeably heavier than the compact I have, but I'm going to get runtime for my trouble w/ negligible loss of torque between the two.
DeWALT also got back to me w/ a charging question I had w/ regards to the XRP nicads. Assuming long periods of non-use, they recommend I put the bats in the charger every 2 weeks. They assure me I won't ruin or degrade my XPR Nicads if I do this (but memory affect and poor nicad performance has been force fed into my head for years so I'm not sure I believe them).

I guess I'd go for the 920KX if I felt confidant that I wouldn't be shopping for new new batteries in a year if I use the drill as I describe. Do you agree w/ DeWALT JC, or do you have your own opinion on things?
